Indicator System
Trip-Indicators
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 accommo-
date 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.
Edison is offering 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 opera-
tion.
