British BS 88 Fuses

General Information

Designed and tested to:

• BS 88: Part 4

• IEC 269: Part 4

• UL Recognized

Cooper Bussmann offers the industry’s widest range of

British style semiconductor fuses and accessories.

Cooper Bussmann British style products use innovative arc

quenching techniques and high grade materials to provide:

• Minimal energy let-through (I

• Excellent DC performance

• Good surge withstand profile

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 240V or less — to take

advantage of their size, performance and cost benefits.

Voltage Rating

All Cooper 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 adapter and microswitch attachment

are available, to provide remote indication. Fuse blocks are

also available for most applications.

High Speed Fuses British BS 88 Fuse Accessories Indicator System CL1 Panel Mount Clips Trip-Indicators CL1 Panel mount fuse clips are available for mounting a trip-indicator when mounting directly on the fuse is impractical. Order part number CL1. Trip-indicators are available for use in parallel with the main fuse. They can either be attached to the associated fuse or mounted separately in panel mounted fuse clips, reference CL1.
