Abstract: According to one aspect, a thermal protection device is provided having an electrical input for receiving input DC power and an electrical output for connection to a load. A heating circuit is coupled to the electrical input for developing one of first and second different heat magnitudes depending upon a temperature magnitude in the housing. An additional circuit is in thermal communication with the heating circuit for providing output DC power to the electrical output when the first heat magnitude is developed and for interrupting the output DC power when the second heat magnitude is developed.
