For other power factor

values, the total clearing

integral can be calculat-

ed as a multiple of the

clearing integrals, the

correction factor K and

the correction factor X.

The ac voltage rating of Cooper Bussmann^®fuses is given in

volts rms. Fuses tested to IEC are tested at 10% above their

rated voltage. British Style BS 88 fuses are tested at 5%

above its rated voltage. UL recognition tests are performed at

the rated voltage.

When fuses are connected in parallel it is recommended that

the applied voltage does not exceed 0.9 U (the rated volt-

When impulse loads are an intrinsic/normal parameter of the

load current either as single pulse or in trains of pulses or

when their level is higher than the melting current at 0.01

seconds (per time-current curve), contact Cooper Bussmann

for application assistance.

When fuses are connected in parallel, one must take into

account that the current sharing is not necessarily equal.

And it must be checked, that the maximum load current is

not exceeded.

In addition to the parameters set forth in the preceding table,

the RMS value of the load current as calculated for any

period of 10 minutes or more should not exceed the maxi-

mum permissible load current.

Series Connection

Fuses in series may not equally divide the applied voltage. It

is recommended that series connected fuses should only be

operated at fault currents that yield melting times less than

10 ms and a recovery voltage per fuse of less than or equal

Furthermore, it is important that a fuse should not be applied

in the non-continuous/dashed portion of the associated

time-current curve.

to 0.9 U (the rated voltage of the fuse).

N

Any time-current combination point which falls in the

non-continuous/dashed portion of the time-current curve is

beyond the capability of the fuse to operate properly.

Mounting Guidance

The recommendations below have to be followed when

mounting a Cooper Bussmann fuse with end plate threaded

holes.

DC Operation

Depending upon the short-circuit time constant and the mag-

nitude of the prospective short-circuit current, the dc voltage

at which a fuse can be applied may be less than its ac rating.

Long time constants require a lower dc voltage. Conversely,

however, higher available prospective short-circuit currents

result in faster fuse openings and thus permit a fuse to be

operated at a higher dc voltage.

The Cooper Bussmann Paul P. Gubany Center in St.

Louis is certified by Britain’s prestigious ASTA

(Associated Short Circuit Testing Authority) to

perform short testing of its own devices designed to

operate to ASTA requirements which are closely tied

to IEC requirements. The Gubany Center is the only

testing facility available in North or South America

for this product certification.

Fig. 2: 70-100A

The Gubany Center has equipment capable of

generating 300,000A of current at 600Vac three-

phase, and 100,000A at 170Vdc, under carefully

controlled conditions. It offers a wider range of

current voltage and frequency configurations than

any other facility of its kind in the world, and is built

to exceed the short circuit capacity of today’s high

power electrical distribution systems.

Cooper Bussmann Named First in

Fuses by Readers of Plant

Services Magazine

Cooper Bussmann has been named as the vendor

offering the highest value in electrical fuses in a

recent fill-in-the-blank survey of nearly 40,000

qualified readers of Plant Services Magazine. A full

70 percent of survey respondents said Cooper

Bussmann was their number one choice. The

nearest competitor weighed in at only 7 percent. The

63 percent spread was the widest of all 63 product

categories, ranging from aerial work platforms to

welding equipment. According to Plant Services

editors, the products chosen are those “that deliver

the combination of functionality, durability and low

maintenance that add up to the lowest estimated

life-cycle cost”—those offering the very best value in

their product category.

Fuse Bases (Blocks)

Modular Style

Cooper Bussmann offers a comprehensive line of fuse bases

that provide the user with design and manufacturing flexibility.

Two identical half bases make up a Cooper Bussmann^®

modular fuse base. These “split” units can be panel mounted

any distance apart to accommodate any length fuse.

Stud Type

The simpler design is the C5268 series modular fuse base.

With this design, the fuse terminal and cable (with

termination) are mounted on the same stud, minimizing labor

needed for installation. The stud type base is available in the

configuration shown in the table below.
