Abstract

See full text

A circuit protection device including a housing (15) defining a chamber (19) and a metal oxide varistor (MOV) stack (310) disposed within the chamber (19). A first spring (330a) is electrically attached at a first end to a first input terminal (311a) of the MOV stack (310) by a solder connection (30) and at a second end to a first input line (20a). The first spring (330a) is biased away from the first input terminal (311a). A second spring (330b) is electrically attached to a second input terminal (311b) of the MOV stack (310) by a solder connection (40) and at a second end to a second input line (20b). The second conductive spring (330b) is biased away from the second input terminal (311b). When an overvoltage condition occurs, heat generated by the MOV stack (310) melts at least one of the first or second solder connections (30, 40) to allow the corresponding springs to be displaced away from the respective MOV stack (310) input terminals (311 a, 311 b), thereby creating an opening circuit.
