Circuit protective device with temperature sensing

The present invention relates to circuit breakers, and more particularly relates to over-current protection for circuit breakers. A temperature sensor for use in a circuit breaker is disclosed. The temperature sensor is included in the circuit breaker and detects temperature of a target within the current path of the breaker. If the temperature of the target falls within a preselected critical range, a trip signal is triggered in a trip processor board which actuates a solenoid to trip the circuit breaker. A bridge is provided in the current path to continue normal function of the circuit breaker outside the critical range of temperatures.
