ABSTRACT:
A multiple circuit thermal circuit breaker comprises a plurality of single circuit breakers which are contained in a housing. A single manually operable control is provided to effect resetting of all the circuit breakers and each circuit breaker includes a temperature sensing means through which the current flowing in the respective breaker flows, the temperature sensing means when the current exceeds a predetermined value acting to trip the respective circuit breaker. Linkage is provided between the circuit breakers so that when one is tripped by operation of its temperature sensing means the other circuit breakers will also be tripped.
