  • Patent number: 10062530
    Abstract: 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).
