This is an electrical auxiliary contact for new GoPact MCCB. GoPact MCCB has a good price-performance ratio for basic applications and delivers a reliable electrical protection for your applications. This auxiliary contact is compatible with GoPact MCCB 400 and 800. Auxiliary contact provides remote information of the circuit breaker status and can thus be used for indications, electrical locking, relays, etc. It is a common point changeover type contact, with a normally open (NO) contact and a normally closed (NC) contact. OF indicates the position of the circuit breaker contacts (open/closed). SD indicates that the circuit breaker has tripped due to an electrical fault (overload, short circuit), or due to the operation of a shunt trip release or an undervoltage release. The conventional free air thermal current [Ith] is 10A. This auxiliary contact is pre-wired with a 500mm length cable with 0.5mm² cross section. It is clipped inside the circuit breaker. GoPact MCCB 400 and GoPact MCCB 800 are IEC 60947-1 and IEC 60947-2 certified. GoPact MCCB range benefits from Schneider Electric quality assurance.
