1. A thermal fuse comprising:

  • a conduction element with first and second ends;

    a sensor in mechanical communication with the conduction element;

    an elastic element adapted to apply force on the conduction element in an activated state of the thermal fuse; and

    a restraining element adapted to secure the elastic element and thereby prevent the elastic element from applying force on the conduction element in an installation state of the thermal fuse, wherein application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the thermal fuse in the activated state.
