THERMALLY TRIPPED CIRCUIT BREAKER WITH ADJUSTABLE TRIPPING SENSITIVITY |
摘要 |
A push button operated circuit breaker with thermal tripping by way of a bimetal strip includes an angled contact bridge which is mounted within a switch housing to be freely pivotal and is urged in a tripping direction by a tripping spring against a contact lug of the bimetal strip projecting laterally for engagement with a contact piece of the contact bridge. The circuit breaker further including a connecting arm which is coupled for movement with the bimetal strip. The cylindrical exterior surface of a drum-shaped rotary body lies against the connecting arm and thus creates a kinematic connection between the rotary body and the connecting arm. When the switch housing is fully assembled, the drum-shaped rotary body is operative as an adjustment eccentric which is externally manipulatable by way of a hexagonal recess so as to adjust the tripping characteristic of the circuit breaker.
