Alarm switch
TRIP-IND (TRIP INDICATOR)
A tripped signal can be output via the floating contact for display via a warning lamp, for
example. This trip alarm switch operates as soon as the residual current exceeds the
response current setting value and has therefore caused the residual current device to trip.
The standard trip alarm switch has changeover contacts and screw-type connections.
The terminal designations of the relevant contact are shown in the diagram below.

The table below illustrates the behavior of pre-alarm and tripped signals on RCD320 or
