SIRIUS - SIRIUS 3RA load feeders Manual, 09/2016, A5E03656507520A/RS-AB/003 21 Product description 3.3 Applications 3.3 Applications Fuseless load feeders can be used anywhere in industry where fuse, contactor, and overload relay combinations were previously used. The increased functionality of the motor starter protector (unlike a fuse combination, it can be used as an EMERGENCY OFF and as a disconnector) means that a fuseless load feeder is capable of solving numerous applications easily. 3.4 Application environment 3RA2 load feeders are climate-proof. They are designed for use in enclosed spaces in which no severe operating conditions prevail (e.g. dust, caustic vapors, hazardous gases). If they are to be installed in dusty or damp rooms, suitable enclosures must be provided. SIRIUS - SIRIUS 3RA load feeders 22 Manual, 09/2016, A5E03656507520A/RS-AB/003 4 Product combinations The SIRIUS modular system supports the assembly of load feeders for a whole variety of requirements.

SIRIUS - SIRIUS 3RA load feeders Manual, 09/2016, A5E03656507520A/RS-AB/003 23 Product combinations SIRIUS - SIRIUS 3RA load feeders 24 Manual, 09/2016, A5E03656507520A/RS-AB/003 5 Functions Pre-assembled load feeders In the 3RA2 fuseless load feeder, the 3RV2 motor starter protector takes on the dual function of overload protection and short-circuit protection. Upstream protective devices such as melting fuses or limiters are superfluous, as the load feeder is capable of withstanding short circuits up to 150 kA at 400 V. The 3RT2 contactor is suitable for extremely complex switching tasks requiring maximum endurance. The trip class on all pre-assembled 3RA2 feeders is CLASS 10. Self-assembled load feeders Thanks to the flexible SIRIUS modular system, load feeders can be assembled for the most diverse requirements. These load feeders can be fuseless or fused. Load feeders for starting motors can be assembled for the following startup types, for example: Direct-on-line start Reversing start Star-delta (wye-delta) start Soft start Configuration with solid-state switching devices for high switching frequencies In the case of a configuration with overload relay, a tripping class up to CLASS 30 can be set.

SIRIUS - SIRIUS 3RA load feeders Manual, 09/2016, A5E03656507520A/RS-AB/003 27 Configuration 6.2 Use of 3RA2 load feeders with highly energy-efficient motors (IE3) 6.2 Use of 3RA2 load feeders with highly energy-efficient motors (IE3) 6.2.1 General information on the startup characteristics of highly energy-efficient motors (IE3) Motor starter protectors have been conceived to protect and switch motors. They assume the task of line protection in the event of an overload or short-circuit. To this end, motor starter protectors are equipped with sensors for overload and short-circuit detection and possess an interruption point for switching motor and short-circuit currents. Without technical adaptation to the new highly energy-efficient motors (IE3), the problems described below can arise. 6.2.1.1 Short-circuit detection In the event of unusually high currents in the electrical installation, short-circuit detection serves to keep the thermal and dynamic load low and ensure safe shutdown. The response threshold should lie above the currents that a starting motor causes. The dimensioning of a system is influenced by the response value. The higher the response value, the higher the chosen cable cross-sections to be protected must be. This increases costs in the system and for the switching devices. This is why the response values have been adapted to the previously typical motor starting currents. The drawback of the new, more efficient motors (IE3) is that, on average, the locked rotor and magnetization currents (inrush currents) arising at the moment of switching on are considerably higher than in the case of the previous generations of motors. The spread of locked rotor and inrush currents is very wide. Motors with high values can therefore cause the motor starter protector's short-circuit detection to respond. This leads to unintentional shutdown ("early tripping") during motor starting. Early tripping can occur whenever the motor current lies in the top range of the motor starter protector's setting scale and a motor with a high inrush current is used. 6.2.1.2 Making and breaking capacity of motor starter protectors Making and breaking capacity tests are conducted in compliance with the standard under three-phase AC loading with 10 to 8 times the rated current. In some cases, the locked rotor and inrush currents of IE3 motors are clearly above these values. In isolated cases, current spikes that arise during switching on can cause brief lifting of the contacts without triggering a breaking operation by short-circuit detection. Where the motor is switched on by a contactor, for example, the motor starter protector's making/breaking capacity is irrelevant. In this case, the motor current is only carried. The current that can be carried without any problems is normally higher than the switching device's making/breaking capacity. SIRIUS - SIRIUS 3RA load feeders 28 Manual, 09/2016, A5E03656507520A/RS-AB/003 Configuration 6.2 Use of 3RA2 load feeders with highly energy-efficient motors (IE3) 6.2.1.3 Rated motor current/setting scale For motor protection, the motor's rated current must be set on the motor starter protector's setting scale. The new IE3 motors generally have lower rated currents. This can lead to situations in which a motor starter protector with a lower rated current has to be chosen for the same motor rating. Thus, the short-circuit detection response value also drops and can lead to tripping during motor starting. See also Short-circuit detection (Page 28) 6.2.2 Optimization of 3RV2 motor starter protectors for IE3 motors The motor starter protectors have been revised in relation to the higher locked rotor currents and inrush currents as follows: Raising of the lower short-circuit detection response tolerances without changes to the maximum values. No change to system dimensioning Increase in the making / breaking capacity. Far-reaching avoidance of restrictions due to increased motor starting currents and inrush currents, see the chapter "Technical modifications/restrictions of 3RV2 motor starter protectors (Page 31)". Adaptation of some motor starter protector versions' overload releases and setting scales. Avoidance of using smaller motor starter protectors due to lower rated motor currents (see chapter "Technical modifications/restrictions of 3RV2 motor starter protectors (Page 31)") In the case of motors with very high locked rotor and inrush currents, problems can arise despite adaptations, e.g. undesired tripping on starting. It is recommended that motor starter protectors be selected such that the setting does not need to be made in the upper range of the setting scale. This reduces power loss in the device (cost saving and reduced temperature rise in the control cabinet) and increases the distance from the short-circuit releases' response limits. SIRIUS - SIRIUS 3RA load feeders Manual, 09/2016, A5E03656507520A/RS-AB/003 29 Configuration 6.2 Use of 3RA2 load feeders with highly energy-efficient motors (IE3) Selection example In this example, two motor starter protectors are compared with each other. Rated motor current: 15 A Motor starter protector A: Setting scale 10 ... 16 A Motor starter protector B: Setting scale 14 ... 20 A Motor starter protector B (14 ... 20 A) is recommended since its power loss is lower and it has a higher distance to the response limits. The power loss of motor starter protector B is approximately 35 % lower than that of motor starter protector A. The response limits of the short-circuit release always refer to the maximum setting value: In the case of motor starter protector A, the response value of the short-circuit release is 208 A (13 x 16 A). At the setting value of 15 A, the distance to the response limit of the short-circuit release is 13.86 times the current setting (208 A / 15 A =13.86). In the case of motor starter protector B, the response value of the short-circuit release is 260 A (13 x 20 A). With a setting value of 15 A, the distance to the response limit of the short-circuit release is 17.33 times the current setting (260 A / 15 A = 17.33). In the present example, the distance to the response limit of 13.86 times the setting current for motor starter protector A increases to 17.33 times the current setting for motor starter protector B.

In the case of both types of coordination, the short-circuit is reliably mastered. the only differences are in the extent of the damage sustained by the device following a short circuit. Type of coordination 1 The load feeder may be non-operational after a short circuit has been cleared. Damage to the contactor and the overload release is also permissible. Type of coordination 2 After short-circuit disconnection, there must be no damage to the overload release or to any other part. The load feeder can resume operation without needing to be renewed. Welding of the contactor contacts only is permitted if these can be separated easily without significant deformation.
