The PE path is established automatically when the housings are connected. An interlock mechanism engages when connecting the trunking units as well as the feeder units with the end caps. Two fixings prevent a loosening of the connections. No expansion compensation is required. Figure 1-3 Connection method CD-K system Tap-off plugs Insulated enclosed tap-off plugs enable access to the current supply via tap-off points on the trunking units. They can be connected and disconnected by hand. Figure 1-4 Tap-off plugs CD-K system The tap-off plugs are available in 3 and 5-pole versions, with and without fuse as well as with connecting cables or plastic cable sleeves. SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 09/2011, A5E01541101-02 15 System overview 1.2 CD-K system Fixing and mounting The trunking unit profile allows attachment of fixing brackets which are also used for installing lighting fittings. They can be attached to any position of the trunking unit. The clearance between the suspension points is dependent on the load and may not exceed max. 3 m. Figure 1-5 Fixing bracket on trunking unit SIVACON 8PS - Planning with SIVACON 8PS 16 Planning Manual, 09/2011, A5E01541101-02 System overview 1.3 BD01 system 1.3 BD01 system System overview The BD01 busbar trunking system is designed for applications from 40 A to 160 A. In the BD01 system, a single size supports 5 rated currents. In other words, all other components can be used across the power range for all 5 rated currents.

The trunking units or end caps are simply inserted into the lower housing of the joint block. Once the upper part of the joint block or end cap is fitted, a secure connection is established by simply tightening the four screws. Figure 1-7 Establishing a safe connection Tap-off units Tap-off units are available in four different sizes to connect the loads and also with various components fitted, e.g. such as plugs, fuses, miniature circuit breakers or combinations of the aforementioned. Figure 1-8 Tap-off unit BD01 system Ancillary equipment units offer additional space for decentral function expansions. Thus, automation and control components can be installed directly on the busbar. SIVACON 8PS - Planning with SIVACON 8PS 18 Planning Manual, 09/2011, A5E01541101-02 System overview 1.3 BD01 system Fixing and mounting The BD01 busbar is installed edgewise, with the tap-off points on the side using fixing brackets on the wall, ceiling or non-fixed installation. The mounting is implemented on the connection points using a universal fixing bracket. The system can also be fitted flat with the tap-off points pointing downwards. This reduces the required fixing interval by half. Figure 1-9 Mounting the BD01 system Fire protection If the busbar trunking system is routed through a fire wall or ceiling, it must have fire protection.

For reasons associated with design, an ancillary equipment unit based on a BD01 ancillary equipment unit is used for the BD01 busbar trunking system. A universal ancillary equipment unit suitable for the application in question is used for BD2, LD and LX systems. Standard applications are factory-assembled prior to delivery by combining tap-off unit and ancillary equipment unit as appropriate. The bus line for the transmission of data signals is laid in a cable channel mounted on the trunking unit.

Accordingly, when dimensioning and selecting electrical equipment such as distribution boards and transformers, rather than focussing on them individually, you need to aim to optimise their performance as part of a combined system. All components have to be dimensioned sufficiently for loads both in rated operation and in the event of a malfunction. Furthermore, you must take the following important issues into consideration when drafting a power supply concept: Building type, use and design (e.g. high rise, low rise or number of storeys) Determination of load centres, identification of possible supply routes and locations for transformers and main distribution boards Calculation of the building's effective installed loads according to specific area loads as appropriate for the building's use Planning authority regulations and requirements Requirements set out by the utility company Requirements to be met by power supply concepts Planning will never produce just a single option for a solution. Rather, you will need to assess a number of possible options on the basis of issues relating to technology and cost. The following requirements are major factors: Simple and transparent planning Long service life High availability Low fire load Flexible adaptation to changes in the building SIVACON 8PS - Planning with SIVACON 8PS 24 Planning Manual, 09/2011, A5E01541101-02 Planning principles 2.2 Busbar trunking system planning The solution: Siemens busbar trunking systems In most applications, these requirements can easily be solved by using suitable busbar trunking systems. It is for this reason that busbar trunking systems are increasingly being preferred to cable trunking by engineering consultants charged with designing systems for power transmission and distribution. Siemens offers busbar trunking systems from 25 to 6300 A: The CD-K busbar trunking system from 25 to 40 A for supplying power to lights and small loads The BD01 busbar trunking system from 40 to 160 A for supplying power to shopfloors with tap-offs up to 63 A The BD2 system from 160 to 1250 A for supplying power to medium-sized consumers in building and industrial applications The ventilated LD system for supplying power to consumers with medium power requirements in industrial applications The LX sandwich system for power distribution to consumers with high power requirements in building applications The LR cast resin system for power transmission under extreme ambient conditions (IP68) Figure 2-1 Siemens busbar trunking systems SIVACON 8PS - Planning with SIVACON 8PS Planning Manual, 09/2011, A5E01541101-02 25 Planning principles 2.2 Busbar trunking system planning 2.2.2 Different types of busbar trunking systems and their functional scope Requirements of the power supply Specific requirements of power supplies and their individual components are typical of modern production facilities and in building technology today. This is particularly true of automated facilities. The ability to retrofit new equipment or modify existing resources without interrupting active production is not only important for the continuous provision of the electrical power supply. It is also a vital requirement for production facilities operating on a multiple shift basis. Increased safety and complex systems require a power distribution system which is able to respond to all requirements associated with costs and technology. The CD-K, BD01, BD2, LD, LX and LR busbar trunking systems are type-tested low-voltage switchgear assemblies (TTA) compliant with DIN EN 60439-1 and -2. The CD-K, BD01, BD2 und LD systems consist of busbars, internal bar fixings, an external enclosure, fixing and connection accessories. The LX sandwich system and the LR cast resin system consist of busbars, fixing and connection accessories and an insulating foil, along with an aluminium enclosure (LX) or an enclosure made from epoxy resin (LR). Figure 2-2 BD2 trunking unit with tap-off unit Power transmission Components of the busbar trunking system transmit power between transformers and low voltage power distribution systems and from the main distribution board to the service distribution board. Trunking units without tap-off points are used for the power transmission. In addition to the standard lengths, customers can select any lengths to meet their particular building requirements. SIVACON 8PS - Planning with SIVACON 8PS 26 Planning Manual, 09/2011, A5E01541101-02 Planning principles 2.2 Busbar trunking system planning Power distribution The main application of busbar trunking systems is power distribution. Current can't be taken from just a single point which is permanently installed such as a cable installation. Current tap-off units can be moved to any position within the entire system. To tap power at any given point simply requires positioning a tap-off unit at that location on the busbar. The result is a flexible distribution system for decentralised power supply to a particular line or area. Tap-off points can be mounted on one or both sides of straight trunking units. Depending on the requirements of the particular application, busbar trunking units with tapoff units for a rated current of 1250 A from a single tap-off point are available for tapping off power and connecting loads. The tap-off units can be equipped with fuses, fuse-switches, miniature circuit breakers or circuit breakers as desired. To be able to change the tap-off units without disconnecting the busbar trunking run, the following requirements apply: Requirements The PE contact on the tap-off unit leads during installation and lags during removal. The parts which are live during installation, removal or connection have complete protection against direct contact (degree of protection IP2x). Installation requires phasing to be correct. The tap-off unit must be isolated during installation and removal.

Network topology Transparent (line topology with load feeders connected in series via tap-off units) Significant cable cluster at feeding point due to point-to-point power supply to loads from central power distribution system Protective devices for loads In the tap-off unit: facilitating direct and immediately traceable assignment to load locally. Centrally in the distribution board: this means that assignment to the load cannot be verified directly. You have to rely on the cable and load being labelled correctly. Space requirements Low High, since correspondingly large distribution boards are needed. Laying criteria (clustering, laying method, current carrying capacity, etc.) have to be taken into account. Retrofitting in the event of changes to load feeders Highly flexible thanks to tap-off points in the trunking units and large number of different tap-off units Time-consuming and expensive. Additional cables need to be laid from the distribution board to the load. Planning and configuration Quick and easy using computer-assisted planning tools Configuration is time-consuming and complex (distribution board and cable dimensioning, cable diagrams, etc.) Dimensioning (current, voltage drop, neutralisation conditions) Complex Very complex Troubleshooting expenditure Low High Fireproof barrier Type-tested, factory-built Dependent upon installation quality on site Functional endurance Functional endurance tested to DIN 4102-12 Dependent upon installation quality on site Electromagnetic interference Low Relatively high for standard cables Installation Few installation accessories and tools, short installation times Extensive installation accessories and numerous tools, long installation times Weight Weighs up to 1/3 of comparable cable weight Up to 3 times the weight of the busbar trunking system Halogen-free, PVC-free 1) All tap-off units are halogen-free and PVC-free.

Power distribution can be planned precisely on the basis of total connected load and the type and number of loads. Planning tools such as SIMARIS design provide assistance. The line topology with load feeders arranged at regular intervals ensures transparency. All applications can be implemented quickly and compactly with standardised sizes. In a cable trunking system, new loads have to On busbar trunking systems, tap-off units in be connected via an additional sub-distributionthe vicinity of loads ensure local transparency. board; this costs both time and money. Increased safety due to high short-circuit rating and minimum fire load. Advanced safety - both in respect of short-circuit rating and where fire load is concerned. BD2A 250 busbar trunking systems, for example, have a fire load of just 1.32 kWh/m, whereas comparable cable trunking systems (NYY 4 x 95/50 mm2) are rated at 5.19 kWh/m. Furthermore, the busbars are halogen-free. Siemens busbar trunking systems feature high short-circuit rating. Furthermore, troubleshooting is made easier thanks to local load shortcircuit protection.

The short-circuit rating of the LD, LX and LR busbar trunking systems is usually higher than the values for the transformer's sustained and peak shortcircuit currents. However, this only applies if just a single transformer is used for the lowvoltage supply. Higher short-circuit values are possible on ring or meshed networks or if transformers are connected in parallel in a low-voltage switchgear assembly. Such scenarios must therefore be given special consideration. Please refer to the technical data for the busbar trunking systems in question for specific data about short-circuit ratings.

Designed for applications involving flexible power supplies and power distribution for consumers in industrial and commercial environments, it can also be used to transmit power from one supply point to another. In addition, the BD2 busbar trunking system can be used as a rising main busbar in high rise buildings. 3.2 System components 3.2.1 Preliminary remark for specifications The BD2 busbar trunking systems can be offered as type-tested low-voltage switchgear and controlgear assemblies (TTA) to DIN EN 60439-1 and DIN en 60439-2. The brand offered represents a complete system consisting of system modules, including elements for connection to the distribution boards such as brackets, straight trunking units, e.g. Z connectors, T connectors, and flexible junction units. Trunking units with tap-off openings can be equipped with coded tap-off units. Tap-off units are protected against incorrect mounting. Depending on the type, the isolation of the tap-off units during removal is assured by a compulsory sequence of operations or by cautionary instructions. If necessary, it is possible to equip the busbar trunking system with an asbestos-free fire barrier which conforms in the case of BD2C to the fire resistance class S 120 and in the case of BD2A to S 90 or S 120. The trunking unit's steel enclosure is made of moulded steel profiles to permit large fixing distances between suspension points. The enclosure is painted in a light grey colour (RAL 7035). The external dimensions may not exceed 68 x 167 mm up to 400 A or 126 x 167 mm up to 1250 A. The connection of the individual systemmodules is implemented with state-of-the-art quick connection terminals with integral compensation for expansion. The system is protected against phase inversion. A mechanical, electrical and maintenance-free connection between two busbar trunking system elements can be established quickly and safely using conventional tools. The conductors are made of aluminium or copper. The aluminium and copper conductors must be nickel-plated and tinned along their entire length. The fire load should not exceed the value stated in the technical specifications. Expansion compensation must be integrated into eachtrunking unit. Busbar trunking units should be able to be mounted both horizontally and vertically. Junction units may not be used to connect cables. Flexible junction unit are permissible as system modules of the busbar trunking system. The following declarations of conformity must be included with the offer: DIN ISO 9001 QA certification Certificates verifying - that the fire barrier has been tested and approved - that functional endurance has been tested and approved SIVACON 8PS - Planning with SIVACON 8PS 40 Planning Manual, 09/2011, A5E01541101-02 Planning with BD2 3.2 System components The general preliminary remarks are followed by a detailed description of the system as appropriate for technical requirements: Technical data for BD2 busbar trunking systems Rated current _________1) Degree of protection IP52/IP54/IP55 2) Mounting position Horizontal/vertical 2) Rated insulation voltage 690 VAC/800 VDC Rated operating voltage 690 VAC Rated frequency 50 - 60 Hz Rated peak withstand current I pk _________1) Rated short-time withstand current Icw (1 s) _________1) Conductor material Al/Cu 2) No. of conductors (active) 5 Fire load _________1) Enclosure dimensions 160 to 400 A 68 x 167 mm 630 to 1250 A 126 x 167 mm 1) Enter data for selected system size. See technical data. 2) Please delete as appropriate. Note The innovative design and construction of the BD2 busbar trunking system means that additional compensation units to compensate busbar expansion are not required. Prevailing length expansion caused by current heat is compensated in the quick connection terminal. Furthermore, regardless of mounting position and degree of protection, the BD2 busbar trunking system can always be loaded at 100% of rated current. This only has to be reduced in the case of pure power transmission in the edgewise mounting position (to 0.9 x Ie).

The incoming supply can be set up as an end feed or a centre feed. 3.2.5.1 End feeder units Common features All end feeder units have the following common features: Cables can be fed in from the front end. Units with cable compartments support cable entry from the side. In the case of multi-core conductor entry, a sectional entry flange with cable sleeves and cable propping bar is standard; in the case of single-core conductor entry, an aluminium plate is standard. The cables are connected using lugs and bolts. The bolts are supplied with the unit.

The sectional entry flange with integrated strain relief can be converted to these positions. Aluminium cable entry plates for single-core cables as an alternative option. The cables are connected using lugs and bolts. When connecting 5conductor cables you will need to remove the bridge between PE and N which will have been fitted prior to delivery.

It is mounted in the centre of a trunking run between two trunking units. A single power supply cable provides power to the left-hand and right-hand trunking runs simultaneously. This means, for example, that a 1000 A centre feed can feed in 2000 A. In such cases you need to pay particular attention to the busbar system's overload and shortcircuit protection. You will need to provide protective measures in the following instances: If short-circuit protection is not being provided by the upstream protective device and/or If the overload is not set by the type and number of loads There are two possible protective measures: 1. Use a centre feed unit with one coupling unit on the left of the incoming feeder and another on the right. The coupling unit is fitted with a protective device (fuse or circuit breaker) providing short-circuit and overload protection. 2. Use two end feeder units located in the centre of the trunking run. The two supply lines are fused separately in the distribution system.

To adapt the busbar trunking system to the actual load, the busbar cross section can be reduced and protected against short circuits and overloads with a coupling unit. Coupling units can be fitted with load disconnect switches up to 630 A or circuit-breakers up to 1250 A as appropriate for the application concerned. The maximum installation length in the busbar trunking run is 1500 mm. The dimensions of the coupling unit must not exceed 1250 x 500 x 500 mm (W x H x D).

The system offers a high short-circuit rating and is particularly suited for the connection of transformers to low-voltage main distribution boards and sub-distribution boards. In applications where high powers are required, conventional systems frequently require the use of parallel cables. The LD system offers optimal power distribution for both horizontal and vertical busbar runs. Coded plug-in tap-off units up to 1250 A that meet extremely high safety standards are available for this purpose. 4.2 System components 4.2.1 Preliminary technical descriptions for specifications The busbar trunking systems should be offered as type-tested low-voltage switchgear and controlgear assemblies TTA to IEC/EN 60439-1 and -2, DIN VDE 0660 Part 500 and Part 502 (German standard), as a steel-encapsulated ready-to-connect system. The distribution systems must be suitable forpower transmission, e.g. between transformer and low-voltage main distribution boards, as well as for power distribution providing a supply of power to an entire area. The brand offered must be a complete system consisting of system modules, including transformers and elements for connection to the distribution boards, as well as such as brackets, straight trunking units and junction units. All components should be available both in straight and offset versions. Trunking units with tap-off openings should be able to be equipped with coded tap-off units. Tap-off units are protected against incorrect mounting. Depending on the type, the isolation of the tap-off units during removal is assured by a compulsory sequence of operations or by cautionary instructions. If required, the busbar trunking system should be capable of being equipped with asbestosfree fire barriers which comply with fire resistance class S 120, and which have been certified by the local or government authority responsible for building standards. The trunking unit's steel enclosure is made of moulded steel profiles to permit large fixing distances between suspension points. Theenclosure is galvanised and painted in a light grey colour (RAL 7035). The external dimensions may not exceed 180 x 180 (240) mm. The individual system modules are connected by hanging a hook from a bolt and tightening a state-of-the-art maintenance-free single-bolt clamp. The conductor between two system units should not be connected with screws. The conductor material is made of aluminium or of copper if the rated current requires. The aluminium conductor must be nickel-plated and tinned, and the copper conductor must be tinned and provided with an additional insulating layer of epoxy-resin. The fire load must not exceed the value specified in the technical data. Junction units with flexible connections or cable connections are not permitted.

See technical data for values. 2) Please delete as appropriate. In accordance with EN60439-1, a reduction of 95% must be taken into account for currents > 800 A at a frequency of 60 Hz. 3) Important planning information The nominal mounting position of the busbar trunking system is horizontal and edgewise for the busbars. In very rare cases, due to a specific trunking run or the option of connecting tap-off units on the side, the busbars might have to be laid flat. The resulting increase in the internal heat rise of the system necessitates a reduction in rated current. The same applies to vertical height rises > 1.3 m (see the table in the next section "Type codes"). The LD busbar trunking system is a ventilated system. When the degree of protection is increased from IP34 to IP54 (enclosed system), the rated current must be derated as specified in the tables in the next section.

To compensate this expansion in length, you need to include expansion compensation units at defined intervals when planning your horizontal installation. With trunking units for vertical installation, the expansion compensation is integrated. When planning horizontal busbar runs, please remember: A straight trunking run without expansion compensation between two junction units must not exceed 10 m in length. A straight trunking run between a junction unit and the end cap must not exceed 25 m in length. In the case of longer trunking run lengths, planning provision has to be made accordingly for expansion compensation units.

Options are: Tap-off point on TOP: ...-AD Tap-off point BOTTOM: ...-ADU Tap-off points on TOP and BOTTOM: ...-ADO+U With a trunking unit with a tap-off point at the TOP and BOTTOM, only one tap-off unit can be used at a time. The required distance between tap-off points is 1 m. The required type should be determined during engineering, based on the mounting position of the busbar. In the case of optional trunking units with tap-off point, a minimum clearance of 0.6 m is required between the end of the busbar and a tap-off point. A coding bracket is located on both sides of a tap-off point. This guarantees noninterchangeability and correct phasing sequence installation of the tap-off units.

These tap-offs are implemented in the form of tap-off units with fuse switchdisconnectors or with circuit breakers. There are basically two types of tap-off unit: With fuse switch disconnector With circuit breaker Figure 4-9 Tap-off unit with fuse switch disconnector and trunking unit with tap-off point Early-make PE/PEN The current tap in the tap-off unit is implemented as an early-make (mounting) or late-break (removal) PE/PEN conductor contact. In a 4-conductor system, this is ensured by a longer PEN bar at the contact mechanism. In a 5-conductor system the PE connection is established via grinding contacts on the coding brackets. Anti-rotation feature and non-interchangeability The coding brackets on the tap-off unit and on the trunking unit's tap-off point (lock-and-key principle) ensure: Non-interchangeability and correct assignment of 4 or 5-pole tap-off units to the associated LD systems Orientation feature to prevent incorrect connections between the tap-off units and tap-off points SIVACON 8PS - Planning with SIVACON 8PS 124 Planning Manual, 09/2011, A5E01541101-02 Planning with LD 4.2 System components 4.2.11.1 Tap-off units with fuse switch disconnector Rated currents Tap-off units 125 A, 2 x 125 A, 250 A, 400 A and 630 A are available for selection. Depending on the current level, LV HRC fuses size NH 00, NH 1, NH 2 or NH 3 are used. The compact dimensions mean that only one enclosure size is required for all rated current ranges. Operator control The tap-off units with fuse switch disconnector are operated by hand using a swivel mechanism. Degree of protection The standard degree of protection is IP30. IP54 degree of protection can be provided as an option. Degree of protection IP30 Degree of protection IP54 Cable compartment/cable entry A bolted connection is used for cables with cross sections up to 2 x 240 mm2. In the standard version, the cable entry is on the front face. Adding a cable compartment enables cable entry from the side. The cables are routed via an integrated cable propping bar in the tap-off unit (cleats to be provided by the customer). The sectional flange plate facilitates the laying of the cables. Opening the tap-off unit Do not open the cable compartment cover until you have removed the fuse switch disconnector handle and, consequently, the fuse. This will ensure that the cable compartment is voltage-free when the cover is removed. The part of the contact device in the front of the tap-off unit is "finger-proof". Type designation The type designation for tap-off units with LV HRC fuse switch disconnectors is LD-.AK/3ST...

Degree of protection The tap-off units have IP54 degree of protection. Opening the tap-off unit The contact compartment and the copper connections between the contact mechanism and the circuit breaker are encapsulated in a finger-proof casing. The cover can only be opened if the breaker has been deactivated. This ensures voltage-free load when the cover is removed. Cable connection On the load side, the outgoing cables are routed directly via the circuit breaker. The PE/PEN conductor is fixed to a bolted connection as appropriate for the cross section. Single-core or multi-core cables can be fed in from the side or via the front face. The sectional flange plate facilitates the laying of the cables.

Regardless of the mounting position, the enclosure ensures IP54 degree of protection (IP55 can be achieved with the appropriate accessories) 1). All units are fitted with either a fuse switch disconnector or circuit breaker with handle as well as bolts for the cable connection. For conductor systems (conductor configurations according to type LX...6.) with insulated PE conductor, the tap-off units are supplied with the addition of a separate PE connection. 1) On request Cable entry Cable entry can be from the side or front (exception: for tap-off units up to 250 A from the front only). Integrated flange with cable sleeves facilitates multi-core cable entry. Aluminium plates are used for single-core cable entry; these have to be fitted with cable glands locally. Safety during operation The tap-off units cannot be opened unless the protective device is switched off manually. Once this is done, the cable connection area is no longer energized. The part of the contact device in the front of the tap-off unit is "finger-proof". Implementing the tap-offs Tap-offs are required for different amperages depending on the sizeand type of consumers involved. These are implemented by means of plug-in tap-off units from 80 to 630 A or junction boxes from 800 to 1250 A.

To calculate the voltage drop in the distance d between the start of a tap and the start of the busbar system, proceed as follows: k = (2 x n + 1 - n x d/L)/(2 x n) Voltage drop diagrams The following diagrams illustrate the voltage drop on the BD2, LD, LX and LR systems taking into account the final heating resistances (in accordance with EN 60439-2) with a load distribution factor - k = 1 for LD, LX and LR - k = 0.5 for BD2 at rated current load. (In the case of a different current diversity factor, the value of the curve must be multiplied by the appropriate distribution factor.)

Fuses and circuit breakers are available for use as protective devices. With the selection of these protective devices the level of the expected short-circuit currents, selectivity requirements or operating and signalling functions are also factors for consideration. When you decide on your short-circuit protection via fuses and circuit breakers you must not exceed the specified short-circuit ratings of the busbar trunking systems. It depends on the level of expected short-circuit current, whether a current limiting protective device is required and what short-circuit breaking capacity the protective device must have.. An overview of the circuit breakers which are able to provide short-circuit and overload protection (400 V and 50 Hz) for the corresponding busbar system appears in the table below 1). The following applies: I"k Icc Icu Type I''k = anticipated short-circuit current at installation location Icc = rated conditional short-circuit current of the trunking run Icu = rated short-circuit breaking capacity of the circuit breaker Rated Circuit breakers Rated short- Circuit breakers Rated short- Circuit breakers Rated short- current with normal circuit with strong circuit current 2) with high circuit switching current 2) switching capacity switching current 2) capacity capacity In Icu A Icc Icu Icc Icu Icc kA kA kA kA kA kA BD2A(C)-160 160 3VL27 16-1... 40 20 3VL27 16-2... 70 20 3VL27 16-3... 100 20 BD2A(C)-250 250 3VL37 25-1... 40 40 3VL37 25-2... 70 50 3VL37 25-3... 100 50 BD2A(C)-400 400 3VL47 40-1... 45 45 3VL47 40-2... 70 45 3VL47 40-3... 100 45 BD2A(C)-630 630 3VL57 63-1DC36 45 45 3VL57 63-2DC36 70 70 3VL57 63-3DC36 100 100 BD2A(C)-800 800 3VL57 80-1SE36 50 3VL57 80-2SE36 70 70 3VL57 80-3SE36 100 100 BD2A(C)-1000 1000 3VL77 10-1SE36 50 3VL77 10-2SE36 70 60 3VL77 10-3SE36 100 60 BD2C-1250 1250 3VL77 12-1SE36 50 3VL77 12-2SE36 70 60 3VL77 12-3SE36 100 60 1) The tripping characteristic of the protective device must be selected as appropriate for the short-circuit rating of the busbar systems, the type of system, the type and number of loads, as well as in line with country-specific regulations and type series. This table contains only a brief overview of BD2 on the use of circuit breakers for protection against short-circuit and overload, and it is intended only as a recommendation. We always recommend that you carry out a calculation using the SIMARIS design network tool to determine the appropriate protection. Please contact our TIP specialists for this purpose. 2) The values for the conditional rated short-circuit current Icc apply for the busbar trunking systems without taking account of the tap-off units.

Calculating the loop impedance of all contributory equipment in a system (incoming power supply, transformers, distribution boards, cable runs, etc.) takes a great deal of time and effort. In this regard, planning time and effort can be reduced significantly by using a dimensioning program such as SIMARIS design which stores the necessary data for most common electrical equipment in a database. 7.1.4 Degrees of protection for busbar trunking systems Use in areas at risk of fire In areas at risk of fire, in accordance with European standard HD 384.4.482 S1, increased requirements are placed on the degree of protection to be afforded for electrical equipment. In the event of a fire risk due to the nature of the materials being processed or stored, if it is possible that dust will accumulate, the minimum degree of protection must be equivalent to IP5X. If dust is not to be reckoned with, national regulations shall apply accordingly. The risk prevention arm of the association of German insurers sets out the following requirements: - In the event of a fire risk due to dust or/and fibres: IP5X degree of protection - In the event of a fire risk due to other readily flammable solid foreign bodies with a diameter of 1 mm or more: IP4X degree of protection SIVACON 8PS busbar trunking systems meet these requirements. They are therefore suitable for such applications.

"Finger-proof" touch protection only applies to the actuator in the actuating direction. Measured from the central point, a clearance with a radius of r = 30 mm must be maintained between the actuator and touch-hazardous parts. IP20 degree of protection is more than "finger-proof" touch protection. It includes touch protection of electrical equipment from all directions. For devices with "finger-proof" touch protection and IP00 degree of protection, direct contact protection can be provided on request in the form of covers.

Examples of these types of building include hospitals and public buildings. DIN VDE 0100-560 relating to buildings and structures for public use and DIN VDE 0100-710 (previously DIN VDE 0107) relating to medical locations specify that the electrical installations in such buildings must maintain functional endurance for specific lengths of time even in the event of a fire. This requirement affects the following equipment in particular: Fire alarm systems Systems for alerting and providing instructions to visitors and employees Emergency lighting Passenger lifts with evacuation circuits that assure functional performance for at least 30 minutes in the incoming cable area under full fire conditions Water pressure boosting systems for the supply of extinguishing water Ventilating systems of safety stairwells, fire department lifts and machine rooms where functioning must be guaranteed for at least 90 minutes. In order to be able to offer the required functional endurance for busbar trunking systems, we have, for example (in some cases working together with Promat), had the BD2, LD, LX and LR busbar trunking systems tested successfully at the Materials Testing Institute at Brunswick in Germany. R& During fire testing the busbar trunking systems concerned (housed in Promatect plate casings of varying thicknesses) were subjected to an external fire load in compliance with the standard temperature curve (STC) in order to evaluate functional endurance to DIN 4102-12.

Accordingly, neither fire nor fumes are permitted to spread from one floor or fire area to another. The BD01, BD2, LD, LX and LR busbar trunking systems can be equipped with fireproof barriers. Fireproof barriers are generally subject to the device standard IEC/EN 60439-2 and national regulations, and these can differ from each other. For this reason, we recommend that you contact your SIEMENS representative in the planning phase. The systems meet the requirements to prove fire resistance periods as per the fire resistance class specifications in ISO 834-1 in accordance with IEC/EN 60439-2. -PD[ r& Figure 7-8 Conditions for busbar trunking systems Permissible temperature increase on components max. 180C Area on fire: Fire in accordance with standard temperature curve DIN 4102, Sheet 2 Permissible temperature increase of escaping air max. 140 C No flammable gases must be allowed to escape.

The fireproofing consists of an inner and outer barrier or an outer barrier only depending on the busbar trunking system. The fireproof barriers are compliant with fire resistance classes S60, S90 and S120 in accordance with DIN 4102-9 dependent upon version and type. The fireproof barrier can be installed in the busbar trunking system at the factory (BD2, LD, LX), added on site (BD01, LX, LR) or omitted completely 1) (LR). 1) Please note the section "Special conditions for the German market". The type of installation is determined by the structure of the busbar trunking system and the required fire resistance class, as you can see from the overview below (the figures ignore the minimum clearances between the fireproof barrier and the wall, and the fireproof mortar): Without external fireproof barrier, in the center of the wall/ceiling With external fireproof barrier, in the center of the wall/ceiling With external fireproof barrier, in the center of the wall/ceiling Examples BD2 with inner fire protection S90 for (wall thickness 15 cm) BD2 with inner fire protection S120 (wall thickness 25 cm) BD2A/BD2C: S120 (wall thickness < 25 cm) LR: S90 1) LR: S120 1) BD01: S90 LD: S120 LX: S120 BD01: S90 (fire protection installed on both sides) LX: S120 Busbar system 1) Fire protection installed from LR system takes place on-site after sealing the wall/ceiling with fillers.

Special conditions for the German market: The versions for fire barriers described here were created on the basis of tests passed in accordance with DIN 4102 Part 9. In Germany, fireproof barriers must possess general planning authority approval. This is issued by the German Institute for Civil Engineering in Berlin. All divergences from general planning authority approval must be clarified with the product manager for the purpose of applying to the competent regional building authority for agreement in individual cases if necessary. Fire safety tests have been carried out successfully for the installation of fireproof barriers in stud walls for the BD01, BD2 and LD systems.

SIVACON 8PS - Planning with SIVACON 8PS 274 Planning Manual, 09/2011, A5E01541101-02 Further information about planning 7.6 Magnetic fields 7.6 Magnetic fields General information Due to their physical characteristics, busbars designed for power distribution and transmission generate pulsating electromagnetic fields in their vicinity with a fundamental frequency of 50 Hz. These magnetic fields can impair the ability of sensitive equipment such as computers or metering instruments to function in full working order. Limits EMC directives and the associated standards do not set out requirements or recommendations for the planning of busbar trunking systems. DIN VDE 0100-710 can be consulted in relation to busbar trunking systems used in hospitals. DIN VDE 0100-710 defines limits for line frequency magnetic fields in hospitals. For example, at 50 Hz, the magnetic induction around a patient's bed must not exceed the following values: B= 2 x 10-7 tesla for EEG B= 4 x 10-7 tesla for ECG The limit for inductive interference between multi-core cables and lines in a high voltage installation (conductor cross section > 185 mm2) and the patient beds to be protected is significantly undershot if the minimum clearance of 9 m recommended in DIN VDE 0100-710 is complied with. When using busbars, this clearance can generally be reduced, since the busbar systems are designed to effectively reduce the magnetic interference fields in the local vicinity. Magnetic field measurements However, in order to facilitate evaluation of the busbars to be used, extensive magnetic field measurements have been taken in accordance with EN 60439-2. The magnetic field emissions of the busbar systems were measured on a straight trunking run 9.0 m long. With the busbars under a balanced rated current load, the magnetic fields were measures in eight directions at intervals of 0.1 m and up to a clearance of 1 m.

Sprinkler systems are automatic fire extinguishing systems. They are designed to detect the outbreak of fire at an early stage and extinguish it as quickly as possible. Once activated for the purpose of extinguishing fire, such systems usually run for at least 30 minutes. The BD2, LD and LX busbar trunking systems are subjected to a sprinkler test. In the absence of a binding standard, the tests were carried out based on a test structure reflecting practical application (see diagram). Test results BD2 and LX All mounting positions of the BD2 and LX busbar trunking systems were tested for water resistance in IP54 degree of protection on the basis of the national risk prevention guidelines for sprinkler systems issued in Germany. Insulation resistance measurements were taken before and after the 90-minute sprinkling period and a high-voltage test was carried out in accordance with EN 60439-2. The equipment passed the test, proving that the busbar system can be put back into operation immediately and without delay once the sprinkler system has run its course. LD The LD busbar system with IP34 degree of protection and the associated tap-off units with IP54 protection were sprinkled with both horizontal and vertical trunking runs with a 3/4" umbrella sprinkler and a 1/2" flat spray sprinkler at a water pressure of 6 bar. In order to be able to assess electrical performance during testing, insulation resistance measurements were taken during the course of the test. No operational failures occurred. Even when subject to extreme water loads such as those associated with sprinkler systems, the LD busbar system is able to remain in full working order. This operational reliability is made possible on the one hand by the generous creepages and clearances and on the other by the fact that water can drain away unhindered.

These rated values apply to specified operating conditions and characterise the suitability of a switchgear assembly. The rated values must always be referred to when combining equipment or configuring switchgear and controlgear assemblies. Rated short-time withstand current (Icw) DIN EN 60439-1; 4.3 As the rms value of the short-circuit current, the rated short-time withstand current characterises the thermal strength of a switchgear and controlgear assembly circuit under a transient load. The rated short-time withstand current is normally determined for a duration of 1 s; divergent time values must be specified. The rated short-time withstand current is specified for the trunking and/or main busbars of a switchgear and controlgear assembly. Rated peak withstand current (Ipk) DIN EN 60439-1; 4.4 As the peak value of the impulse current, the rated peak withstand current characterises the dynamic strength of a circuit in a switchgear and controlgear assembly. The rated peak withstand current is specified for the trunking and/or main busbars of a switchgear and controlgear assembly. Rated conditional short-circuit current (Icc) DIN EN 60439-1; 4.5 The conditional rated short-circuit current corresponds to the uninfluenced short-circuit current that a circuit in a switchgear and controlgear assembly, protected by a short-circuit protective device, can carry without damage (for a certain time). The conditional rated shortcircuit current is therefore specified for tap-off units and/or infeeds with circuit breakers, for example. Rated impulse withstand voltage (Uimp) DIN EN 60947-1; 4.3.1.3 This is a measure of the strength of the air paths in the interior of the switchgear in relation to transient overvoltages. Suitable switchgear can be used to ensure that deactivated parts of a system cannot transmit overvoltages from the line on which they are used.
