Terminals
Note
Cables for the following terminals must be routed separately from the main circuits. Their
maximum cable length is 300 m.
A number of auxiliary contacts which perform a broad range of functions are located
underneath the contact hazard protective cover.
Alarm switch
Floating auxiliary contacts for 3 different alarms are provided:
● AL1
Signaling switch for pre-alarm threshold 1. This auxiliary switch operates as soon as the
residual current exceeds 30 % of the operating current setting value.
● AL2
Signaling switch for pre-alarm threshold 2. This auxiliary switch operates as soon as the
residual current exceeds 60 % of the operating current setting value.
● TRIP-IND (TRIP INDICATOR)
A tripped signal can be output via this auxiliary switch for connection to a warning lamp,
for example. The switch operates as soon as the residual current reaches or exceeds the
response current setting value and has therefore caused the residual current device to
trip.
The standard auxiliary switches for pre-alarms and tripped signals have changeover contacts
and screw-type connections.
