Introduction to Medium Voltage Fuse Link Technology
Offering unparalleled short-circuit interruption capabilities, Medium Voltage (MV) current-limiting fuse links are the principle
protection device used by electrical utilities and switchgear manufacturers throughout the world. Safe, reliable, environmentally
friendly and cost effective, MV fuse links are the protection device of choice for distribution circuits due to their speed of
operation and current limiting ability in the event of a short-circuit fault.
The diagram below shows the operation of a fuse link interrupting a short-circuit fault, achieving a current zero well within the
first half-cycle of a fault. Energy let-through into the site of a fault maybe typically only 1/500th of that of any other type of
switching device.
The speed of operation reduces the effect of short-circuit currents, dramatically limiting the energy delivered to the faulted
circuit, preventing the catastrophic results of high faults and disturbing voltage arcs. The fuse link operation significantly limits
the arc-flash hazard at the fault location. Improved power supply quality also results from the use of fuse links. High fault
currents are interrupted in a few milliseconds, minimising voltage dips in system supply voltage.
Glossary for Medium Voltage Fuse Links
The following is a brief introduction to medium voltage fuse link technology. Some of the terms are also used in other areas of
fuse technology.
Current rating/Rated current, In-The rated current of the fuse link, given in amps.
Derating - A reference to the fact that all MV fuse links must be derated once they are placed in a confined
space, for example when mounted in switchgear. The fuse link must be derated to take into account the effect of
heating on element resistance. Typically a fuse link is derated by between 5-20% depending on application.
Test Duty, TD - A term used to refer to a specific type test within the IEC standard. Test Duty one (TD1),
short-circuit test, Test Duty two (TD2), maximum arc energy test and Test Duty three (TD3), low overcurrent test.
Minimum Breaking Capacity Current, MBC, I3- The minimum current the fuse link can interrupt safely, without
assistance from switchgear with instantaneous striker tripping.
Minimum Fusing Current (MFC) - The minimum current which will cause the fuse link elements to start to melt.
I2T - The minimum value of pre-arcing and maximum value of total clearing energy a fuse link will allow to pass
through it during short circuit operation, expressed as an amount of current (I2), multiplied by time in seconds.
Watts Loss - The power dissipation of the fuse link at a stated value of load current.
Breaking Capacity, I1- The maximum short circuit current the fuse link has been tested to in accordance with
test Duty one (TD1), expressed in kA.
Resistance - The resistance of the fuse link in free air at (20oC), measured in mΩ.

Introduction to Medium Voltage Fuse Link Technology
The main standard covering Medium Voltage (MV) fuse links is IEC 60282-1, 2009. IEC defines MV as from 1kV to 72.5kV.
Current-limiting MV fuse links, split into three internationally recognised types: Back-Up (or sometimes called partial range), fuse
links, which will interrupt any current from their rated breaking capacity down to a minimum breaking current, specified by the
manufacturer. General Purpose MV fuse links will interrupt all currents that will melt the elements within one hour. Full Range
MV fuse links can interrupt any current below the rated breaking capacity that melts the fuse elements satisfactorily.
The diagram below illustrates the three performance criteria in terms of their minimum breaking current I3.
Current-limiting MV fuse links are similar in construction to Low Voltage (LV) cartridge types. Fuse elements do need to be much
longer however to safely interrupt a medium voltage short-circuit. This is achieved by winding the elements round an internal
core or holder, often called a star-core or spider; using this technique a one metre length element can be accommodated in a
250mm length body. The elements are surrounded by a pure, highly compacted granular quartz filler.
Like a LV fuse link, a MV fuse link has a ceramic body. Most current-limiting MV fuse links are also fitted with a striker
mechanism. This is used to operate the trip bar or mechanism in a fuse-switch combination, fuse-switch or ring main unit (RMU)
to achieve low overload fault interruption and three-phase disconnection.
Typically striker mechanisms are driven by a spring mechanism, triggered by a thin striker wire or striker coil running the length
of the fuse link, connected in parallel to the fuse link elements. The striker coil is of much higher resistance than the fuse link
elements, so a current only flows through the striker coil when the fuse link elements melt. The current heats up the striker coil
and this in turn melts the wire retaining the spring, releasing it and pushing out the striker.

Introduction to Medium Voltage Fuse Link Technology
Non-Current Limiting
Essentially, non-current limiting fuse links have short elements and incorporate some means of lengthening the arc after the
element melts, extinguishing the arc and preventing re-ignition. These are known as expulsion fuse links.
Expulsion fuse links are an effective way of protecting overhead distribution lines and transformers. They are designed for
outdoor use only and comprise a tin or copper fuse element in series with a flexible braid in a tube. The tube forms one side of
a triangle, with a latched connection at the top and a hinge at the bottom. The braid emerges from one end of the fuse link and
is held in tension by a spring downwards under gravity. Under fault conditions, the fuse link swings downwards, the arc is
lengthened, extinguished and prevented from restriking.
Thermal Effects of Low Overload Faults
During overload faults lasting a long time, it is possible for medium voltage (MV) elements to get very hot prior to actually
melting. Given that silver has a melting temperature of 960oC, for fuse links with no temperature limitation, this can result in a
fuse barrel temperature of over 400oC and 180oC at the insulating surface surrounding the fuse. To prevent deterioration of the
insulation and to the fuse link itself, all MV fuse links should incorporate some form of technology to limit the thermal stress-
heating, that is possible under prolonged low overload faults, often referred to as temperature limiting technology.
Since the launch of its first MV fuse links almost half a century ago, Cooper Bussmann has employed M-effect technology to
achieve temperature limitation throughout its MV fuse link range. A small mass of special low melting point alloy is added to
each fuse element, this has the effect of drastically reducing the temperature of the MV fuse link during operation. The larger
cross section of the fuse link elements, made possible by use of this feature, ensures cooler running and lower power
dissipation under normal service conditions than comparable temperature limitation technology.
Other manufacturers employ a temperature-limiting (or thermal) striker to overcome their overheating problems. In general with
this approach the maximum temperatures reached by the fuse link and its surrounding insulation are not as low as with the use
of M-effect. Such a solution is no more effective than use of M-effect on the fuse link elements and moreover does not bring
the additional advantages of lower watts loss, cooler running and greater withstand against transient surge currents.
When a Cooper Bussmann fuse link operates under low overload fault conditions the maximum temperature rise of the fuse
link is such that the temperature of the surrounding synthetic insulation remains below the temperature limits for all insulated
fuse switchgear. The fuse barrel therefore remains intact and the fuse carrier and its contacts remain unimpaired.
Typically a Cooper Bussmann MV fuse link of a given rating may run 10-30oC cooler than comparable fuse links which
do not employ M-effect. This advantage is particularly useful when the MV fuse link is used in totally enclosed all insulated
switchgear, such as cast resin fuse-switches or compact SF6 insulated Ring Main Units (RMUs), or GIS HV switchgear, since
less derating is required and hence a smaller rating of MV fuse link will do the same job as a higher rated MV fuse link from
another manufacturer.
In short M-effect fuse links are generally safer, give better protection and are longer lasting than alternative designs, which do
not employ these valuable features.

Introduction to DIN Medium Voltage Fuse Links
Cooper Bussmann ‘T’ Range
The Cooper Bussmann ‘T’ range medium voltage current-limiting fuse links to dimensional standard DIN 43625, are one of the
most advanced design of medium voltage fuse links available anywhere in the world today. Developed by Cooper Bussmann,
they comply with the very latest requirements of IEC 60282-1, are lead and cadmium free (meeting the RoHS and WEE
directives) and have been designed to meet current and future global electrical utility specifications.
The ‘T’ range offers time-current characteristics that are optimised to improve discrimation with upstream devices, giving fast
clearance of earth faults in secondary terminal zones. The fuse links utilise Cooper Bussmann M-effect technology, ensuring low
power consumption during operation, while at the same time providing temperature limitation in the event of an overload
fault.
The fuse links are suitable for both indoor and outdoor applications and are fitted with a spring striker. This gives either an
output force of 80N with a travel of 30mm in the case of fuse links with part number sequence ‘E’, or in the case of part number
referring to ‘S’, a spring striker with an output force of 50N and a maximum travel of 26mm.
Cooper Bussmann ‘F’ Range
The ‘F’ range fuse links have ‘full range’ clearing capability. Cooper Bussmann ‘F’ fuse links types are designed to clear low
overloads right down to the fuse links’ rated current in accordance with latest IEC 60282-1 requirements. They are thus suitable
for use as a sole form of protection. ‘F’ range time-current characteristics are especially advantageous for transformer protection
applications.
Cooper Bussmann ‘A’ Range
This earlier, well proven, design has values of minimum breaking current between the ‘T’ and ‘F’ range including higher current
ratings.
Applications
MV DIN fuse links are suitable for primary side transformer protection, fuse switch combination unit, fuse bases and fuse
switches.
Fuse links comply with DIN dimensional
standard DIN 43625.
‘F’ Range, high performance full range fuse
links.
‘T’ Range, high performance back-up fuse
links, with striker tripping.
‘A’ Range, including high current rating
back-up fuse link.
Comply with IEC 60282-1 and VDE 0670
part 4.
Wide variety of ratings, 3.6kV to 36kV.

Features & Benefits
Certification. The Cooper Bussmann Medium Voltage (MV) DIN range of fuse links has been fully tested and certified.
Interrupting performance has been certified at the world class independent test laboratories of KEMA. All other performance
requirements such as temperature-rise, time-current characteristics, weather sealing etc. have been thoroughly tested to ASTA
approval procedures.
All Cooper Bussmann medium voltage DIN fuse links exhibit cool running and low power dissipation during normal operation
in service. The use of M-effect (as already explained), drastically reduces the temperature of the fuse link during
operation. The larger cross section of the fuse link elements made possible by using M-effect ensures cooler running and low
power dissipation under normal service conditions. This ensures maximum levels of network efficiency by reducing
unnecessary power loss and minimizing switchgear wear and tear due to the fact the fuse link is running much cooler during
its service life.
Cool operation. When Cooper Bussmann MV fuse links operate under low fault conditions, the maximum temperature rise of
the fuse link is well within the temperature limits for all switchgear due to the use of M-effect, ensuring fuse carrier contacts
remain unimpaired, thereby increasing the life cycle of the substation and so reducing capital and maintenance costs.
Silver elements. All Cooper Bussmann Back-Up MV fuse links use 99.8% pure silver in their elements, ensuring high
conductivity and low power (revenue) loss, maximising network efficiency.
Reduced nuisance operation due to surge currents. The use of M-effect allows a larger element cross section for a given
current rating, improving withstand capability against transient overcurrents due to transformer magnetizing inrush current,
reducing mal operation. This improves system reliability reducing maintenance costs.
Low arc voltages during short-circuit operation. Cooper Bussmann MV fuse links are designed to produce low levels of arc
voltage, allowing fuse link to be used down to half their rated voltage, so during short-circuit operation, the switchgear and
cables are not unduly stressed by being exposed to high arc voltages, thereby prolonging the life of the switchgear and
improving asset utilization.
Additionally, stock holdings and part numbers can be reduced, as a 24kV Cooper Bussmann MV DIN fuse link can be used
on a 12kV system. Utilities that run a mixed voltage network (say 24, 15.5, 13.8 12 and 10 kV) can standardise on one type of
switchgear with one type of fuse link, reducing costs and removing the need for an additional fuse extension and
inventory.
Construction. All electrical connections within the Cooper Bussmann MV fuse link are made by welded or brazed joints. This
firstly ensures a very mechanically robust fuse link and secondly, greatly reduces the risk of poor intermittent internal
contacts, improving substation reliability.
X-Ray. All Cooper Bussmann MV fuse links are X-rayed during production. Element alignment, M-effect position, etc are all
checked by trained operators. This process ensures defects that would not normally be detected by purely visual or electrical
based quality systems, to be captured during production.
Element Design. Unlike many other medium voltage fuse link manufacturers, Cooper Bussmann medium voltage fuse elements
employ a “neck” or ‘notch’ design principle as opposed to a perforated element design principle, see diagram below.
This element design insures that even the smallest degree of accidental element damage is easily detected during testing, as
part of the manufacturing process thus avoids the possibility of such imperfect fuses being put into service. This is far more
difficult to achieve with perforated element designs.
Lead and Cadmium Free. All Cooper Bussmann ‘T’ Ranges fuse links are lead and cadmium free and meet with the latest
WEEE and RoHS directives. RoHS is less than 1000Vac.
Recycling Scheme. Cooper Bussmann operates a recycling scheme for all medium voltage fuse links, please contact
buletechnical@cooperindustries.com for further information.

Selection of these MV fuse links has been based on the following:
1 - The fuse link should withstand transformer magnetising inrush currents, taken as 12 times full load current for 0.1
seconds.
2 - The fuse link should discrimate with the rating of the secondary fuse link stated or where only individual cable exit
protection exists, the highest LV fuse link rating likely to be used.
3 - The fuse link should operate within two seconds for transformers complying with IEC 60076-5 in respect of
impedance, voltage and short-circuit withstand current.
4 - The fuse link should operate reasonably quickly in the event of a transformer internal fault or an earth fault in the
secondary terminal zone of the transformer.
5 - In the case where there is no secondary fuse link for overload protection, the minimum recommended MV fuse link
rating applies to the use of fuse links in encapsulated enclosures where permissible continuous overload is generally
limited to 120% of transformer full load current. However, if greater overload currents are permissible a higher
rating of fuse link may be required. Where the fuse link is used in open air or conditions of unrestricted ventilation a
higher permissible overload may be possible.
6 - In most cases more than one rating of MV fuse link is recommended for a particular transformer size. Choice of fuse
link will then depend on which fuse link offers the best protection; e.g., having one fuse link for several transformer
sizes.
Recommendations for other voltage are available on request, please email buletechnical@cooperindustries.com.

Introduction to Medium Voltage Motor Fuse Links
Cooper Bussmann Motor Fuse Links
Cooper Bussmann range of motor fuse links are designed to meet the specific requirements necessary for motor protection.
During the starting cycle of direct on-line motors, the fuse elements will reach a considerably higher temperature than during
normal operation; this is due to the high amount of current the motor will draw as it starts, typically, 6 times its normal load
current value. This results in expansion and contraction of the fuse elements and could cause premature operation of the fuse
link. Cooper Bussmann motor fuse links encompass an advanced design to minimise this effect. This therefore, negates the
need to over specify the fuse rating due to high values of motor starting current.
Cooper Bussmann fuse links operate extremely quickly under heavy fault currents, resulting from the time-current characteristic.
Low power dissipation ensures low temperature rise, important in multi-tier starters for example. Switching (Arc) voltages are
lower than permitted values, therefore, 5.5kV fuse links are also suitable for 4.8kV and 2.4kV circuits.
Application
Fuse links provide short-circuit protection in motor circuits to both the motor starter and cables from the starter to the motor.
Overload protection is provided by the motor starter, generally by an overload relay and contactor. Combination striker tripping
may also form part of the associated equipment which houses the fuse links and motor starters.
Application Procedure
For any motor the fuse current rating is determined by magnitude and duration of starting current, except in a few situations
where the starting currents are very light.
Motor Fuse Links comply with IEC 60282-1,
IEC 644 and BS 5907.
Available in DIN 43625 and BS 2692 dimensions.
Sold in a wide range of ratings from:
3.6kV - 5 to 450A
7.2kV - 5 to 355A
North American dimensioned products also
available, 2R to 24R ratings.

Direct-on-Line Starting
In the absence of specific information, the starting current can usually be taken to be six times the motor’s full load current.
The starting time will depend on the type of the drive but will be approximately as follows:
Pump motors - 6 seconds
Mill motors - 10 to 15 seconds
Fan motors - 60 seconds
These are average values and the appropriate figures for starting current and starting time for actual installation should be
obtained wherever possible.
Multiply the starting current by 1.7 and using this value of current and the starting time, (it is recommended that a minimum time
of five seconds be adopted), plot this point on the time-current characteristics of the fuse link. The correct current rating of the
fuse link is then chosen as being the one immediately to the right of the point plotted. The chosen fuse link must also have a
current rating of at least 1.3 times the full load current of the associated motor.
The rating chosen will be adequate for normal applications where the associated motor is not started more than twice in a given
period of one hour.
For applications using more frequent starting duties, a greater derating factor must be applied as shown below:
Maximum 2 starts per hour - Derating factor 1.7
Maximum 4 starts per hour - Derating factor 1.9
Maximum 8 starts per hour - Derating factor 2.1
Maximum 16 starts per hour - Derating factor 2.4
Assisted Starting
A similar method of fuse selection may be used as for direct-on-line starting (see above), but it must be noted that the normal
running current of the motor is likely to be closer in value to the nominal current rating of the fuse link than for direct-on-line
applications.
The rating of fuse link chosen will need to be appreciably greater than the motor running current to allow for restricted cooling
inside control gear cubicles, particularly where multi-tier starters are involved. In case of doubt refer to Cooper Bussmann for
further guidance.
Notes
For applications involving more frequent starting duties than 16 times per hour or where unusual duty cycles are involved,
consult Cooper Bussmann application engineers for advice: buletechnical@cooperindustries.com or 00 44 (0) 1509 882 699.

Introduction to Medium Voltage and Auxiliary Transformer Fuse Links
Cooper Bussmann Voltage and Auxiliary Transformer Fuse Links
Cooper Bussmann manufactures a wide range of voltage transformer (VT) fuse links. In North America they are referred to as
Potential Transformer fuse links. These fuse links are designed for use in the primary side of voltage transformers to provide
system isolation in the event of faults occuring in the transformer circuit.
Voltage transformer fuse links have a preferred current rating of 3.15A. Experience has shown that there is a risk of spurious
operation by transient overcurrents where lower current ratings are used. In addition, in order to minimise the risk of deterioration
of the fine fuse elements caused by corona, it is desirable to mount the fuse links so that the earthed metal is not in the
immediate vicinity of the part of the barrel between the ferrules.
Higher current and ‘E’ ratings are available for special applications, including auxiliary transformers.
A range of VT fuse links with a breaking capacity of 200kA for use at the output terminals of large turbo alternators can also be
ordered. For further information, please contact Cooper Bussmann application engineers: buletechnical@cooperindustries.com.
Types prefixed ‘A’ or ‘N’ are suitable for use indoors in air only. Types prefixed ‘O’ may be used under oil.
Application
Small rated fuse links for protection of voltage and auxiliary transformers. Back-up protection up to 3.15A and voltages from
1.1kV to 36kV.
British Standard Voltage and Auxiliary Transformer
(VT) fuse links.
A range of voltage transformer primary fuse links to
BS 2692-1 and IEC 60282-1.
Wide range of ratings from 1kV to 36kV.
3.15 Amp industry standard current ratings.
CAV range with ratings from 3.6kV to 38kV.

Introduction to Current Limiting Fuse Links for Use in Oil Switchgear
Cooper Bussmann Under Oil Fuse Links
Cooper Bussmann range of oil tight fuse links are designed for use in oil filled switchgear. This type was pioneered in the UK.
Cooper Bussmann range has been in continuous manufacture for almost 40 years, being by far the most widely used device of
its kind in the world. Over 1,000,000 Cooper Bussmann branded fuse links have been put into service without a single reported
case of oil ingress. A unique triple seal system ensures against long term seal deterioration. Low power dissipation ensures long
running in oil filled switchgear.
Application
Oil medium voltage fuse links are suitable for primary side transformer protection and oil filled switch combination unit.
The range is not suitable for use inside oil filled transformer tanks where high oil temperatures may be expected.
Application Procedure
For any transformer the fuse current rating is determined by magnitude and duration of inrush current.
General Guide to the Selection of Oil Tight Fuse Links for Use in Primary Circuit of Three Phase Transformers
Fuse Links comply with IEC 60282-1, BS 2692-1
and ESI standard 12-8.
7.2 and 12kV Fuse links tested at highest system
voltage and approved by the UK Electricity Association
approvals panel.
Voltage ranges from 3.6 to 24kV.
Fitted with powerful pyrotechnic striker pin.

Selection of these fuse links has been based on a compromise between the following:
1 - Withstand against magnetising inrush current is taken as 12 times full-load current for 0.1 second.
2 - Withstand against 150% permissible overload current. Recommendations marked with the following:
* Limited to permissible overload of 130%
** Permits use of a 12kV OHFMA 80A fuse link with a 1000kVA transformer where permissible overload does not exceed 130%.
3 - For 6.6kV systems, 12kV fuse links are recommended where possible in the interests of standardisation.
4 - Wherever possible, 254mm long fuse links are offered rather than equivalent 359mm types
5 - The above recommendations are not generally applicable to transformers feeding motor circuits with starting currents in excess of the
transformer full load current. In this event please consult Cooper Bussmann application engineers: buletechnical@cooperindustries.com.

General Guide to the Selection of Air Fuse Links for use in the Primary Circuit of Three Phase
Transformers
Selection of fuse these links has been based on a compromise between the following:
1 - The fuse links should withstand transformer magnetising inrush currents, taken as 12 times full load current for 0.1 seconds.
2 - The fuse links should discriminate with the highest rating of secondary fuse links
3 - The fuse links should withstand periodic overcurrents of up to 150% of transformer fuse load current
4 - The fuse links should operate reasonably quickly in the event of a transformer inter-turn fault or a fault in the secondary
terminal zone of the transformer
Notes
a) The above recommendations are not generally applicable to transformers feeding motor circuits with starting currents in
excess of the rated current fuse. In this event, please consult Cooper Bussmann application engineers.
b) For 6.6kV transformers, 12kV fuse links are recommended, where the required current rating is available.
* Where the transformer is not subjected to periodic overcurrents, a lower fuse rating may be suitable, fuse ratings marked with
“*”, are only suitable for use with the transformer sizes quoted, where significant over loading does not occur.
Fuse links for use in transformers with primary voltages of 3.3, 22 and 33kV are available, please consult Cooper Bussmann
application engineers for further details buletechnical@cooperindustries.com.

Expulsion Fuse Links for Use in High Voltage Distribution Cut-Outs
Cooper Bussmann Expulsion Fuse Links
Cooper Bussmann expulsion fuse links have been widely used throughout the world for over 40 years. They have in that time
built up a formidable reputation and consistency of performance.
Cooper Bussmann expulsion fuse links are designed to be interchangeable with other types of manufacturers cut-out units and
are available in several patterns.
Application
Expulsion fuse links current ratings should be selected on the basis of maximum expected transient no damage currents rather
than on full load current. In addition, the selection of higher current ratings will reduce the possibility of supply interruption due
to transient surges such as those due to lightning strikes (for information on our Surge Protection Device SPD, please contact
buletechnical@cooperindustries.com.
Links should be handled with a reasonable degree of care when installing. Excessively rough handling may damage the element.
It is normal, under certain fault conditions, for arc extinguishing material and/or metal particles to be expelled from the fuse
assembly. It is therefore recommended that reasonable precautions be taken to prevent the installation being approached by
unauthorised persons.

ASL - Automatic Sectionalising Links
Cooper Bussmann Automatic Sectionalising Link ASL (Smart Links)
Cooper Bussmann low cost retrofit Automatic Sectionalising Link (ASL), represents a significant breakthrough in the field of high
voltage overhead line distribution system protection. It is a completely self-contained device designed for use with multi-shot
circuit breakers or auto-reclosers. The ASL was originally developed by Cooper Bussmann from invention by the Electrical
Council Research Centre, now EA technology in the UK.
Cooper Bussmann ASL ensures effective overhead spur line isolation in the event of a geniune local fault, while at the same time
remaining unresponsive to transient (temporary) no-damage surge currents, caused by electrical storms etc, see figure 1.
How the Sectionaliser Works
The sectionaliser houses a logic circuit in its main conductive carrying tube. This ensures the electronic circuitry is free from
electrical interference, as the tube acts as an effective Faraday cage and is powered by a small current transformer mounted on
the outside of the carrier tube.
Statistics show that 90% of expulsion fuse operations on spur lines are in response to transient no-damage faults and that the
cost for each expulsion fuse link replacement can be of the same order as the capital cost of a complete fuse cut-out. The
alternative approach favoured by some Utilities of replacing expulsion fuse links by solid links has the major disavantage that
any permanent fault on a spur line results in an outage of the whole system.
Cooper Bussmann ASL provides an economic solution to the problem, by ensuring effective spur line isolation in the event of a
geniune local fault, while at the same time remaining unresponsive to transient no-damage surge
currents.
Low cost retrofit option for spur line isolation in place
of existing expulsion fuse links.
Available for up to 33kV lines.
Standard pick-up current ratings of 20, 25, 40, 50,
63, 100 Amps.
Other ratings up to 320 Amps available.
Available in single or 3-phase ganged arrangements.

SECTIONALISER'S
MEMORY
Operation is accomplished by discharging a capacitor into a small chemical actuator (or ‘striker’) which unlatches the carrier tube
and causes it to swing down. The ASL is reset by fitting a replacement actuator and re-inserting the carrier into its mount.
The logic circuit is designed to inhibit response to transformer magnetising inrush current surges and induced current waves
resulting from electrical storms. Therefore, in practice any spur line fault condition which persists for a time of several seconds
will operate the ASL, so isolating the spur as illustrated above. Any transient or ‘no damage’ current will be ignored.
Operational Sequence
The logic circuit on the printed circuit board within the ASL is powered by a small current transformer mounted on the outside of
the conductive carrier tube. Under normal load conditions the printed circuit board remains inert. However, should the line
current increase above a certain pre-set value (the pick-up current) the logic circuit activates. The upstream auto re-closer then
opens, temporarily removing the fault from the line. The logic circuit, powered by an internal capacitor, stores the incident for
around 25 seconds (the ‘reclaim’ time). When the upstream device re-closes, some three to ten seconds later, if the fault current
is no longer in evidence, the ASL will ignore the incident and eventually reverts to an inert state again. However if the fault
current (i.e. a current above the pick-up value) is still present, the logic circuit will decide that this represents a permanent fault
on the spur line and will prepare to de-latch. The logic circuit is however, inhibited form operating the latch mechanism until the
upstream recloser has tripped for the second time and the line current has fallen to a value of less than 300mA (the ‘hold-off’
current) for a period of at least 0.1 second. The ASL thus operates during the dead time of the upstream protective device and
does so quietly, without sparks or ionised gas emission and without contact erosion.

Mounting Arrangements
The contact assemblies of the ASL are adjustable to allow for use with a variety of types of expulsion fuse mount. Alternative
upper contact assemblies are available. These can be either fitted to the ASL during manufacture or may be provided loose as
conversion kits. ASLs can also be provided complete with suitable ‘fuse mounts’ where required.
Applications
The ASL must be used in conjunction with either an upstream circuit breaker having multi-shot reclose facility or an auto-
recloser. In either case the dead time of the device must be appreciably less than the 25 second ASL reclaim time.
The most useful pick-up current setting is likely to be 100A. This will allow protection of spur line loads totalling up to 1000kVA
3-phase (11kV).
Where the total load is smaller and greater sensitivity to low level faults is required, one of the alternative lower settings can be
supplied. It should be noted that the recommended pick-up current setting is approximately twice the value of the maximum load
current of the connected downstream transformers.

Boric Acid Fuse Links
Medium Voltage Fuse Links Full Line Catalogue
Introduction
Cooper Bussmann BBU medium voltage Boric Acid fuse link and complementary fuse mount or cut-out package is an expulsion
fuse link style fuse, complete with a single-pole porcelain fuse mount offering medium voltage protection for indoor and outdoor
applications.
The fuse mount is available at either 17 or 27kV and is designed to withstand the most hazardous environmental conditions.
The contact system is made from a copper alloy ensuring a long service life in the field.
The fuse mount already has the outdoor fittings, so simply adding a Cooper Bussmann BBU fuse link will deliver a complete
outdoor transformer protection solution.
Cooper Bussmann range of BBU fuse links can be used indoors as well as outdoors. A muffler attachment can be ordered to
limit noise and contamination to indoor equipment during operation.
BBU fuse links are designed to be interchangeable with other leading manufacturers and are available from 17kV through to
38kV, from 3 to 200 amps, with K, E and SE time-current characteristics.
Boric Acid fuse link employs calibrated silver elements combined with boric acid crystals for its interruption media.
The mechanical utilisation of the spring and rod mechanism creates an interruption technique that offers mild exhaustion during
fault interruption.
Boric Acid fuse links are ideally suited to provide distribution transformer protection within electrical distribution networks.
Features of BBU Fuses
A complete distribution transformer package from a single source. Cooper Bussmann offers a single source for all of your
protection needs, both fuse links and fuse mount are fully interchangeable with other manufacturers product lines.
Sealed fuse links - All BBU fuse links are sealed from moisture ingress, preventing deterioration of performance in the fields and
improving overall network reliability while reducing costs.
Fully tested - Cooper Bussmann BBU fuse links are tested to both ANSI C.37 and Australian standard AS1033.1, which due to
Australia’s unique landscape and harsh climate, is widely regarded as the most onerous type test of expulsion fuse link style
protection in the world today.
Single piece end fittings - Cooper Bussmann fuse link package comes with single piece end fittings, reducing set-up time in the
field and lowering inventory, thereby improving network productivity.
Single wrench installation - The fuse links are designed to be installed with a single type of tool, again reducing maintenance,
replacement and installation costs.
Other features to improve safety and overall reliability induce the use of a Nichrome strain element, to reduce susceptibility to
spurious operation in the field caused by vibration and corona, a glass expoxy tube, preventing warping during long time
exposure and permanent date marking facilitating a more robust Operation and Maintenance regime.

Boric Acid Fuse Links
Medium Voltage Fuse Links Full Line Catalogue
Operation
BBU expulsion fuse links utilise the proven performance of boric acid to create the de-ionizing action needed to interrupt the
current. Fault interruption is achieved by the action of an arcing rod and a charged spring, elongating the arc through a boric
acid chamber upon release by the fuse element.
At high temperatures, boric acid decomposes, producing a blast of water vapor and inert boric anhydride. Electrical interruption
is caused by the steam extinguishing the arc, as the arc is being elongated through the cylinder.
Higher particle turbulence of the boric acid causes the rate of de-ionization in the cylinder to exceed the ionization of the
electrical arc. Both high and low current faults are interrupted in the same manner with no foreign material other than the boric
acid required. This enables the fuse to interrupt short-circuit within one half cycle and prevents the arc from restriking after a
current zero.
After interruption, the gases are expelled from the bottom of the fuse.
The arching rod is prevented from falling back into its original position by a friction stop at the top of the fuse unit.
When the fuse operates, the upward motion of the spring forces the top of the arcing rod to penetrate the upperseal, striking the
latch mechanism.
On indoor applications, this action caused the blown fuse indicator to actuate.
When replacing the blown fuse link, the end fittings should be removed from the operated fuse unit, and if undamaged, clamped
onto the new fuse unit.
Application
The BBU Boric acid fuse provides effective protection for circuits and equipment which operate on voltage system up to 34.5kV.
They can be used on industrial distribution systems and all fuses are designed for use on the following:
Power transformers
Feeder circuits
Distribution transformers
Metal-enclosed switchgear
Pad mount switches
BBU fuse units can be used in indoor applications, and can be used to directly replace competitive equivalent units.

Boric Acid Fuses
Outdoor BBU Mount
Outdoor BBU Fuse Fitting
Outdoor end fittings are made of a cast-copper plated
alloy. A large hook eye on the upper fitting allows for
easy installation into pole-top mountings with a hook
stick. The pivotal design of this hook eye provides for
proper engagement of the upper live part. The positive
locking action of the latch mechanism prevents
detachment from the mounting due to shock or vibration.
In the event of a fault, the arcing rod will penetrate
through the upper end of the fuse unit, and cause the
latch to release. Once released, the fuse will rotate down
into the drop-out position to indicate a blow fuse
condition. The lower end fitting has two cylindrical posts
that insert into the lower live part of the mounting. These
posts allow the fuse to rotate into the proper engaged
position, and suspend the fuse during a blown, drop-out
condition.

Fuse Dimensions
Application Notes
Low currents, usually referred to as overload currents, must be considered as BBU fuses have a rather low thermal capacity.
They cannot carry overloads of the same magnitude/duration as motors and transformers of equal continuous currents. For this
reason, the BBU fuse must be sized with the load current in mind so the fuse does not open on otherwise acceptable overloads
and inrush conditions. Coordination should be considered to help determine what type of fuse is applied. The BBU fuse
interrupts at a natural current zero in the current wave and allows minimum of a half-cycle of fault current to flow before the fault
is cleared. The time-current characteristics associated with a BBU fuse has a rather gradual slope making it easier to coordinate
with downstream equipment. In addition, the BBU is ideal for higher voltage (up to 38kV) and high current applications (up to
200A). It is important to examine the minimum melting and total clearing time-current characteristics of this fuse.
Standards
Cooper Bussmann does not compromise when performance, quality and safety are involved. Exacting standards have been
established relative to the design, testing and application of expulsion type power fuses. Compliance with these standards
ensures the best selection and performance. The BBU Power Fuses are designed and tested for compliance to global standards
such as ANSI and Australian Standard AS1033.1 1990.ANSI (American National Standards Institute) is a non-profit privately
funded membership organization that coordinates the development of the US voluntary national standards.
Testing
Cooper Bussmann BBU Power fuse links and fuse mounts were tested in compliance to the standards listed below. This testing
was carried out in independent test laboratories in Canada and in Australia by recognised independent power testings
laboratories. Thermal and interrupting testing was conducted at 17, 27kV. The entire series of tests was conducted in a specific
sequence as stipulated by governing standards without any maintenance being performed. All tests results are verified by
laboratory tabulations and oscillogram plots.
