ABSTRACT:
A resettable circuit breaker has a pair of normally closed contacts through which a load is connected to a power line and means for opening the contacts in response to a predetermined change in electrical current flowing to and from the power line. One of the contacts is mounted on a rocking member which is maintained between a pivot on the base of the apparatus and the armature of a latching solenoid responsive to the predetermined current change by a spring assembly which causes the rocking member to rotate about the pivot means thereby opening and closing the contacts depending on the position of the armature.
