  • Patent number: 7109840
    Abstract: A protector (10) particularly useful for wye-connected three phase electrical motors has a header (12) mounting first and second terminal pins (14) to which L-shaped pin heaters (16) are mounted along with stationary electrical contacts (16b). A generally U-shaped heater and support member (18) has two leg ends welded to the header intermediate to the terminal pins and a snap acting thermostatic disc (20a) is welded through a weld slug to the central portion of the heater and support member. First and second movable electrical contacts (20b) are mounted on the bottom surface of the thermostatic disc positioned to move into and out of engagement with respective stationary contacts upon snapping of the thermostatic disc from one dished configuration to an opposite dished configuration in dependence on temperature of the disc.

  • Patent number: 6756876
    Abstract: A current interrupter (10, 10′) includes bimetallic member (18) as a switching member having a formed portion (18a) providing snap action movement between oppositely dished configurations. An integrally formed extended length portion (18b) having a stiffening feature extends from the formed portion and mounts a movable contact at its free end. Stiffening feature embodiments include folded opposed marginal edges and one or more longitudinally extending ribs formed in the extended length portion. In one embodiment, the bimetallic member is cantilever mounted in a housing member (14). In another embodiment, a bimetallic member (18D) has first and second extended length portions (18b) extending from opposite sides of a formed portion to provide a circuit interrupter with a double break system.
