British BS 88 Fuse Accessories – Indicator System

Trip indicators

Trip indicators are available for use in parallel with the main fuse (Fuse ratings of 20 A and below cannot usually accommodate a trip-indicator).

They can either be attached to the associated fuse or mounted separately in panel mounted fuse clips (reference CL1).

A push-on adapter and microswitch attachment is available for use with the trip indicator to give the facility of remote indication (reference MAI [back termination] and MBI [side termination]).

When a trip indicator is to be attached to the main fuse an accessory pack comprising a pair of mounting clips and an appropriate trip indicator would be required. The clips are snapped onto the fuse end caps and the indicator is pressed into clips as shown.
