ABSTRACT:
An electrical circuit breaker comprises a metal base having a raised step to which an elongated compensator bimetal is welded. A metal cover is secured to the base but is insulated therefrom. An elongated armature bimetal is welded to a step in the metal cover and is substantially parallel to the compensator bimetal. The high expansion sides of both the compensator and the armature face downwards, towards the base. An insulated heater wire is wrapped around the armature and is electrically connected between the armature and the base.
