Zusammenfassung:	A circuit protection device including a housing defining a chamber and a metal oxide varistor (MOV) stack disposed within the chamber. A first spring is electrically attached at a first end to a first input terminal of the MOV stack by a solder connection and at a second end to a first input line. The first spring is biased away from the first input terminal. A second spring is electrically attached to a second input terminal of the MOV stack by a solder connection and at a second end to a second input line. The second conductive spring is biased away from the second input terminal. When an overvoltage condition occurs, heat generated by the MOV stack melts at least one of the first or second solder connections to allow the corresponding springs to be displaced away from the respective MOV stack input terminals, thereby creating an opening circuit.
