Abstract: A thermal trip assembly for use with a busbar includes a fastener, an insulating sleeve, a temperature sensor structured to sense a temperature of the busbar, and a thermal trip circuit structured to output a trip signal based on the sensed temperature. A portion of the insulating sleeve is disposed between the temperature sensor and the busbar. The fastener couples the insulating sleeve and the temperature sensor to the busbar with the insulating sleeve being in direct contact with a portion of the busbar.
