Alarm Switch
The alarm switch accessory monitors the circuit breaker trip status and is
used to provide a remote warning signal indicating that the circuit breaker
has tripped. This signal can be a horn, pilot light, or some other indicator.
The contact on the standard alarm switch is open when the circuit breaker is
in the off or on position and is closed when the circuit breaker is in the tripped
position.
Alarm switches are actuated when the circuit breaker has tripped as a result
of an overload, short circuit or shunt trip operation. See the wiring diagram
in Figure 8.
Auxiliary Switch
The auxiliary switch accessory monitors the circuit breaker contact status
and provides a remote signal indicating whether the circuit breaker
contacts are open or closed. When the circuit breaker is OFF or tripped, the
auxiliary switch with an “A” contact is open and the auxiliary switch with a
“B” contact is closed. When the circuit breaker is on, the auxiliary switch
with an “A” contact is closed and the auxiliary switch with a “B” contact is
open. See the wiring diagram in Figure 7.
