British BS 88 Fuse Accessories - Indicator System
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.
CL1 panel mount clips
CL1 panel mount fuse clips are available for mounting a trip indicator when mounting directly on the fuse is impractical.
Order part number CL1.
