2 General Applications Rated Voltage The AC voltage rating of Cooper Bussmann fuses is given in volts rms. Fuses tested to IEC are tested at 5% above their rated voltage. British Style BS 88 fuses are tested at 10% above its rated voltage. UL recognition tests are performed at the rated voltage. Rated Current Rated current is given in amps rms. Cooper Bussmann fuses can continuously carry the rated current. Power Factor For other power factor values, the total clearing integral can be calculated as a multiple of the clearing integrals, the correction factor K and the correction factor X. X Melting Characteristic The melting 10 characteristic shows the virtual 10 melting time in 3 seconds as a function of the 10 prospective current in amperes rms. 10 The fuses are 1 specially constructed for 10 short-circuit 0 protection against high level fault 10 1 currents. Loading and operation of 10 the fuse in the noncontinuous/dashed 10 3 section of the melt curve must be avoided. The curve can also be read Prospective Current In Amperes RMS as the real melting time as a function of the RMS value of the pre-arc current. Virtual Pre-Arcing Time In Seconds Clearing Integrals The total clearing I t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I t is found by multiplying by correction factor, K, given as a function of applied working voltage, E g, (rms) K E g Arc Voltage This curve gives the peak arc voltage, U L, which may appear across the fuse during its operation as a function of the applied working voltage, E g, (rms) at a power factor of 15%. Power Losses Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, K p, is given as a function of the RMS load current, I b, in % of the rated current. Cut-Off Current A fuse operation relating to short-circuits only. When a fuse operates in its current-limiting range, it will clear a shortcircuit in less than 1 cycle. Also, it will limit the instantaneous Peak Let-Through Current A B COS U L Eg Kp I 0.1 b % Prospective Current in Amps RMS peak let-through current to a value substantially less than that obtainable in the same circuit if that fuse were replaced 9 Courtesy of Steven Engineering, Inc.-30 Ryan Way, South San Francisco, CA Main Office: (50) Outside Local Area: (800)

3 General Applications with a solid conductor of equal impedance. A asymmetrical current B symmetrical current Parallel Connection When fuses are connected in parallel it is recommended that the applied voltage does not exceed 0.9 U N (the rated voltage of the fuse). This is due to the fact that the energy released within the fuses may be unevenly shared between the parallel connected barrels. 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. 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 to 0.9 U N (the rated voltage of the fuse). Mounting Guidance The recommendations below have to be followed when mounting a Cooper Bussmann fuse with end plate threaded holes. 1. Screw in studs: 5 N m Max, 3 N m Min. Attachment of the fuse to bussbar by means of nut and washer: Thread Torque (N m)* Configuration Max Min , M , M , M *1 N m = lb-ft Overloads The design of Cooper Bussmann fuses is such that they can be operated under rather severe operating conditions imposed by overloads (any load current in excess of the maximum permissible load current). In applications, there will be a maximum overload current, Imax, which can be imposed on the fuse with a corresponding duration and frequency of occurrence. Time durations fall into two categories: 1. Overloads longer than one second. Overloads less than one second termed impulse loads. The following table gives general application guidelines which, in the expression Imax < (% factor) x I t. I t is the melting current corresponding to the time t of the overload duration as read from the time-current curve of the fuse. The guidelines in the table below determine the acceptability of the selected fuses for a given I max. Frequency of Occurrence Overloads (> 1 sec) Impulse Loads (< 1 sec) Less than once per month I max < 80% x I t I max < 70% x I t Less than twice per week I max < 70% x I t I max < 0% x I t Several times per day I max < 0% x I t 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. 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 maximum permissible load current. Furthermore, it is important that a fuse should not be applied in the non-continuous/dashed portion of the associated time-current curve. 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. DC Operation Depending upon the short-circuit time constant and the magnitude 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 shortcircuit currents result in faster fuse openings and thus permit a fuse to be operated at a higher DC voltage. Consult Cooper Reduction Factor Bussmann for additional information and application assistance when 1.0 fuses have to operate under DC conditions. 0.9 Load Current Versus Conductor Cross Section (IEC cross section) Reduction of permissible load current when the conductor cross section is less than that given in IEC Publication 9-1 & valid for Cooper Bussmann high speed fuses. Application Assistance If you have application problems or need a fuse outside our standard program, please contact the nearest Cooper Bussmann representative.

Their unique design and construction provide: Minimal energy let-through (I t) Low operating temperature Low watts loss Square body style fuses are a very attractive solution for high power applications which require a compact design with superior performance. The construction and design of square body style fuses make it easy for Cooper Bussmann to manufacture custom products. Our cataloged offering provides only a sample of the wide variety of product which is available. Each square body style fuse is available with a number of different end fittings. Options include: DIN 3 53 DIN 3 0 Flush End (Metric/US) French Style US Style Voltage Rating All Cooper Bussmann square body style fuses are tested to IEC 09: Part. This standard requires a test voltage which is 5% higher than the rated voltage. In North America, fuses are required to clear only their rated voltage. Accessories Square Body style fuses are available with three different open fuse indicator systems. Options include visual indication and indication utilizing a microswitch. Fuse blocks are also available for most applications. 11 Courtesy of Steven Engineering, Inc.-30 Ryan Way, South San Francisco, CA Main Office: (50) Outside Local Area: (800)

23 Square Body Applications Maximum Permissible Load Current The rated current value of Cooper Bussmann fuses is based on the ambient temperature in the space immediately below the fuse of 0 C. The following graph gives correction factors (k) for a range of temperatures ( 0 C to +80 C). Maximum permissible continuous load currents can be calculated by applying the following formula: I b I n k ( V) x K b where I b = Maximum permissible continuous load current I n = Rated current of fuse k = Temperature correction factor v = Velocity of cooling air in m/s (max. 5 m/s). K b = Fuse load constant k Temperature Correction Curve C The maximum permissible continuous load current Ib of a fuse can be checked empirically (i.e., by satisfying the formula below) by making simple voltage and temperature measurements under actual operating conditions after the fuse has been installed in its operating location and loaded at the calculated Ib value: E ( t) N E 1 where E 1 = Voltage drop across fuse after 5 seconds E = Voltage drop across fuse after hours t = Air temperature at start of test ( C) N = Constant Fuse Rated Voltage (IEC) N High Speed Fuses Body Cross Section Standard fuse program includes barrels with different cross sections.
