The terminal designations of the relevant contact, the maximum rated voltage and the
current carrying capacity are shown in the diagram below.
Each relay contact has a maximum rated operational current of 5 A at 230 V AC. Since the
terminals have a maximum current carrying capacity of 13.5 A, the current flow across the
common terminal (01C = Common) must be limited to 13.5 A when all three signaling
switches are used.
The relays for the pre-alarm signals (AL1 and AL2) drop out again as soon as the residual
current reaches or exceeds the relevant pre-alarm thresholds.
The relay for the tripped signal (TRIP-IND) drops out again as soon as the residual current
device is reset again by means of the molded case circuit breaker handle, or the handle of
the manual or motor operator.
Since the relay for the tripped signal (TRIP-IND) is a bistable relay, the relay contact states
remain "stored" even in the event of a power outage. When the power supply recovers, the
indicated relay contact states are those which existed before the power outage.
