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. A push-on adapter and microswitch
attachment is available for use with the trip indicator to
give the facility of remote indication, reference MAI.
Fuse ratings of 20A and below cannot usually
accommodate a trip-indicator.
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.

We offer a microswitch, complete with 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 in the range of temperatures
associated with standard operating conditions and during
fuse operation.
