Abstract

A disconnect switch is disclosed with an integrated thermal breaker that can be disposed between a source of power and a circuit to be protected. The disconnect switch can comprise a housing, a first terminal coupled to a power source and a second terminal coupled to a load. The first terminal and the second terminal can be partially included in the housing. The disconnect switch comprises a bi-metal thermal conductive element made from at least two metal sheets with different thermal expansion coefficients and having a concave shape that engages the first and second terminals. Upon occurrence of an overload condition, heat flowing through the bi-metal thermal conductive element causes the concave shape to retract to a convex shape and disengage the bi-metal thermal conductive element from the first and the second terminals.
