PowerPact B-Frame 15 to 125 A Circuit Breakers Accessories and Auxiliaries Auxiliary and Alarm Indication Contacts Auxiliary Switch (OF) / Alarm Switch (SD). Indication contacts provide remote information of the circuit breaker status and can thus be used for indications, electrical interlocking, relays, etc. They are 1A1B common point changeover type contacts, with a normally open (NO) contact and a normally closed (NC) contact. Open/Closed - Auxiliary Switch (OF) Indicates the position of the circuit breaker contacts. Trip Indication - Trip Alarm Switch (SD) Indicates that the circuit breaker has tripped due to: an electrical fault (overload, short circuit) the operation of a shunt trip or an undervoltage trip the push-to-trip button. The activation of the push-to-trip button resets when the circuit breaker is reset.
