ABSTRACT:
A circuit breaker assembly, which is responsive to both current overload and thermal overheat or over-cold, includes a circuit breaker switch containing a current release device arranged in a housing to be responsive to a current overload and operative to permit a respective contact spring to move a corresponding movable contact away from a fixed contact upon the occurrence of a current overload and independently of the position of a switching rocker; and a thermal release actuator received in the housing for can automatically providing an actuating action to operate another respective contact spring to move another corresponding movable contact away from another fixed contact when a temperature of a predetermined surrounding zone is overheated or over-cold. The circuit breaker further includes at least a thermal detector disposed within the surrounding zone for breaking a current flowing therethrough when a temperature therearound is overheated or over-cold that reaches a predetermined temperature; and a connecting circuit for electrically connecting the thermal detector in parallel with the circuit breaker switch.
