Abstract
The disclosure relates to a three phase aircraft circuit breaker in which a single push-pull manual operator controls a single mechanical latch for the three poles. Slidable contact carriers in each of the phases are controlled by thermally actuated latches in each of the poles which are released upon the occurrence of an electrical overload by a current responsive bimetal in each pole. An ambient temperature responsive bimetal is provided in each phase. A common trip mechanism effects opening of all poles of the circuit breaker upon the occurrence of an overload in any phase.
