Abstract

The invention relates to a circuit breaker with temperature detection function. The circuit breaker comprises a box body which is made from the insulating flame resistance material, wherein the box body also comprises a first circuit break unit containing an actuating mechanism used to realize the on-offs of the load and the power circuit in normal condition, a temperature sensor which is used to detect the inner temperature of the box body and output the detection signal of a characterization temperature value, and a second circuit break control unit which is used to control the first circuit break unit to generate the circuit break action, when the temperature value exceed a threshold.
