ABSTRACT:
A circuit breaker comprises a compensator bimetal and a main bimetal which deflect in the same direction when heated. Each bimetal carries an electrical contact, which are normally in contact with each other. Upon overload, the contacts open. However, opening of the contacts causes electric current to flow through a heater wire wrapped around the armature bimetal, thereby keeping the main bimetal deflected and keeping the contacts apart.
