CIRCUIT BREAKER WITH AMBIENT COMPENSATION

摘要

A circuit breaker comprises a current responsive tripping bimetal and a pair of compensating bimetals in latching engagement with each other to compensate for movement of the current responsive tripping bimetal in response to changes in ambient temperature. The circuit breaker is a multi-pole circuit breaker with a current responsive tripping bimetal in each pole and one pair of compensating bimetals in only one of the poles.
