Circuit Breaker Alarm Operation:
1
Provides an alarm during an electrical or manual trip condition.
2
Provides an alarm during an electrical trip condition only.
3
Extended shunt leads are 22 AWG stranded wire, approximately 7-10 ft. long from exit point at bottom of
distribution cabinet. Each shunt lead is equipped with a 49.9 ohm current limiting resistor. Shunt leads are
factory wired to SM-DU+ (if ordered).
Note:
Electrical Trip only circuit breakers are not typically used for battery disconnect circuit breakers.
