ABSTRACT:
A heat generating means, such a resistive element, is serially connected in a current-carrying conductive line, and a fusible link carrying current from said line is serially mounted between the line and said resistive element and is positioned in proximity to the heat generating means, to be heated by the heat from the generating means and to melt in response thereto, thereby breaking the serial connection in the current-carrying line. A spring means may be provided to urge disconnection of the serial circuit when the fusible link melts.
