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. Rated Current Rated current is given in amperes rms. Cooper Bussmann fuses can continuously carry the rated current. Melting Characteristic The melting characteristic shows the virtual melting time in seconds as a function of the prospective current in amperes rms. The fuses are specially constructed for short-circuit protection against high level fault currents. Loading and operation of the fuse in the non-continuous/dashed section of the melt curve must be avoided. The curve can also be read as the real melting time as a function of the RMS value of the pre-arc current. 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 I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (rms). 2 104 6 4 2 103 6 4 2 102 6 4 2 Virtual Pre-Arcing Time In Seconds 101 6 4 2 100 6 4 2 10–1 6 4 2 10–2 6 4 2 10 –3 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.

When a fuse operates in its current-limiting range, it will clear a short-circuit in less than 1⁄2 cycle. Also, it will limit the instantaneous peak let-through current to a value substantially less than that obtainable in the same circuit if that fuse were replaced with a solid conductor of equal impedance. 105 Peak Let-Through Current 0.2 Eg 100 200 300 400 500 600 660 104 103 A B 2≈ 10 2 102 103 104 Prospective Current in Amperes RMS 105 106 A asymmetrical current B symmetrical current 88 For product data sheets, visit www.cooperbussmann.com/products/datasheet.asp High Speed Fuses General applications Parallel Connection When fuses are connected in parallel it is recommended that the applied voltage does not exceed 0.9 UN (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 UN (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 2. Attachment of the fuse to buss-bar by means of nut and washer: Thread Configuration 5 ⁄16” – 18, M8 3 ⁄8” – 16, M10 3 ⁄8” – 24 1 ⁄2” – 13, M12 1 ⁄2” – 20 *1 N•m = 0.7375 lb-ft Torque (N•m)* Max Min 25 20 45 40 45 40 65 50 65 50 Frequency of Occurrence Less than once per month Less than twice per week Several times per day Overloads (> 1 sec) Imax < 80% x It Imax < 70% x It Imax < 60% x It Impulse Loads (< 1 sec) Imax < 70% x It Imax < 60% x It — 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 short-circuit currents result in faster fuse openings and thus permit a fuse to be operated at a higher dc voltage. Consult Cooper Bussmann for additional information and application assistance when fuses have to operate under dc conditions. Load Current Versus Conductor Cross Section 1.0 Reduction Factor High Speed Fuses 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 2. Overloads less than one second termed “impulse” loads. The following table gives general application guidelines which, in the expression Imax < (% factor) x It. It 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 Imax.

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.

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. Catalog Max Fuse Stud Stud Dia.
