ABSTRACT:
A temperature sensitive circuit interrupting arrangement includes a temperature controlled relay that will open to disconnect a load, such as a common household appliance or utensil, from a power source when the amount of heat produced by any one of a plurality of electrically conductive items coupling power from the power source to the load causes a sensed temperature to rise above a pre-determined safety limit temperature. The rise in the sensed temperature may be due to a poor (resistive) contact, an over-current condition due to a malfunction of the load, or other common causes. The circuit interrupting arrangement may be incorporated in many forms of electrical devices including male plugs, female sockets, switches, dimmers, multi-outlet power strips, power cords, and ground fault interrupters.
