Abstract: An apparatus for latching a door having a latching member; a retention cam wherein the retention cam further comprises an extended face and is rotatable about its axis; a spring; a locking member; an actuator; a push out member; and a driving member; wherein the actuator drives the driving member to remove the locking member from contact with the retention cam and the driving member drives the push out member to push the latching member away from the retention cam. The apparatus is capable of assisting both in the latching and unlatching of the device.

Abstract: 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.
