The MOT mobile unit is configured to receive a power from a brake line of the train that runs a length of the train, wherein the power is derived from a compressed air in the brake line by means of an air-powered generator that recharges a battery.
A circuit interrupting device with a temperature activated permanent lockout trip mechanism is provided. The temperature activated permanent lockout trip mechanism is located in close proximity to a section of conductor that generates heat. An energized first solenoid generates a magnetic force capable of moving an armature that unlatches a latch releasing a spring to open a main contactor removing power from an electrical circuit. The temperature activated permanent lockout trip mechanism upon reaching a predetermined temperature which is higher than the predetermined temperature threshold of the temperature sensing switch also generates a mechanical force capable of moving the armature that unlatches the latch releasing the spring to open the main contactor removing power from the electrical circuit. Once activated, the temperature activated permanent lockout trip mechanism inhibits the latch from latching which prevents a reset of the circuit interrupting device thus the circuit interrupting device is permanently disabled as the main contactor cannot be closed, and power no longer be reconnected to the electrical circuit.
