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 (I²t)
• 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.
