British BS88 Fuse Accessories

Trip indicators

Bussmann Trip Indicators by GD Rectifiers

Bussmann’s 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.

Fuse ratings of 20A and below cannot usually accommodate a trip indicator.

When a trip indicator is attached to the main fuse, an accessory pack featuring a pair of mounting clips and a trip indicator would be required. The clips are snapped on to the fuse end caps and the indicator is pressed into the clips.

Microswitch Adapter - MAI and MBI

Bussmann Microswitch Adapter by GD Rectifiers

Bussmann offer a microswitch adapter for securing the indicator. The microswitch is provided with double pole, single throw contacts, having both a normally open and a normally closed position. A special material has been employed in the construction of the adapter to provide reliable operation within the range of temperatures associated with standard operating conditions during fuse operation.


MAI – back terminal orientation

MBI – side terminal orientation
