摘要：An automatic circuit breaker here includes a mechanism for manual opening and closing of the contacts, and an overcurrent release. Auxiliary release means is also included for opening of the contacts, as in response to a detected ground fault. The overcurrent release includes a latch that is caused to deflect laterally in response to an overcurrent, and the mechanism includes a shiftable latch part having a lateral surface that engages an abutment part of the overcurrent latch. Deflection of the latch, or retraction of the latch part effects release of the circuit breaker. An electromagnet has an armature for operating the shiftable latch part. The armature is located close to the shiftable latch part in the closed configuration of the mechanism, but there is no possible interference by the armature with any of the operating paths of the circuit breaker mechanism.
