Abstract: A circuit-interrupting system for interrupting an electrical current to a device is provided including a relay assembly configured to be operable in a closed state when a sensed temperature is below a predetermined threshold, thereby maintaining electrical current to the device, and an open state when the sensed temperature is above the predetermined threshold, thereby interrupting the electrical current to the device. A heater element is provided proximal to said relay assembly and configured to activate at least the open state of the relay assembly. At least one sensor in electrical communication with the heater element is provided disposed remote from the relay assembly and being configured for sensing temperatures, wherein when the sensed temperature at said at least one sensor is above the predetermined threshold, the at least one sensor is configured to cause the heater element to activate the open state of the relay assembly.

Abstract: An electrical device including a heat sensing interrupter to enable a load to be selectively coupled to or disconnected from a power source in accordance with a level of a sensed temperature includes a relay assembly operable between a closed state when the sensed temperature is below a predetermined limit temperature, thereby enabling the coupling of the load to the power source, and an open state when the sensed temperature is above the predetermined limit temperature, thereby electrically disconnecting the load from the power source. The device further includes a sensor assembly including a light source operatively associated with a light sensor. The light sensor is configured to be sensitive to specific levels of the sensed temperature and the light source is configured to emit light along a plurality of optical paths at any one of a plurality of wavelengths sensitive to temperature.

Abstract: An electrical receptacle has an outlet and senses the operating temperature and automatically turns off when the temperature rises above a predetermined threshold. The receptacle has a reset button that must be manually operated to enable operation of the outlet to resume.

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.

Abstract: An electrical safety device is provided with a heat responsive relay adapted to be interposed between a load and a power source. The relay is adapted to open circuit in response to a predetermined temperature. A heater element responsive to the opening of the relay is shunted across the relay. When the relay opens, power is shunted to the heater for maintaining the relay at least at the predetermined temperature thereby holding the relay open while the load remains connected to said power source.
