General Information Designed and tested to: • BS 88: Part 4 • IEC 269: Part 4 • U.L. Recognized Bussmann offers the industry’s widest range of British style semiconductor fuses and accessories. Bussmann British style products use innovative arc quenching techniques and high grade materials to provide:

British style fuses are typically found in equipment manufactured in the United Kingdom or British Commonwealth countries. However, North American manufacturers have begun to specify British style fuses — particularly in UPS applications at 240 volts or less — to take advantage of their size, performance and cost benefits. Voltage Rating All Bussmann British style fuses are tested to IEC 269: Part 4. 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 Trip-indicator fuses are available for use in parallel with the main fuse. Indicator fuses can be attached to the associated fuselink, or mounted separately in panel-mounted fuseclips. In addition, a push-on adaptor and microswitch attachment are available, to provide remote indication. Fuseblocks are also available for most applications. Voltage 240 150 690 450

Electrical Characteristics Total Clearing I2t The total clearing I2t 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, E g , (RMS).

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, Ib , in % of the rated current .
