Abstract:
1. A self heating thermal protector for a recessed incandescent fixture comprising: an enclosure, a temperature sensitive switch located within the enclosure comprising a temperature sensitive movable element and an electrical contact integral thereto aligned to contact a fixed electrical contact, the contacts of the temperature sensitive switch capable of being preset to open at a desired temperature by movement of the electrical contact integral with the movable element away from the fixed contact, a heat source located in proximity to the enclosure housing the temperature sensitive switch, and thermally conductive potting compound encapsulating both the enclosure having the temperature sensitive switch and the heat source located in proximity to the enclosure wherein restricted air flow over the thermally conductive potting compound effects opening of the electrical contacts during heating of the thermally conductive potting compound by the heat source, and wherein said enclosure housing said heat source, said temperature switch and said thermally conductive potting compound is physically separated from a recessed incandescent fixture.
