Abstract: Featured is a current interruption device including first and second terminal members, each terminal member having at least first and second through apertures and a terminal portion. The first and second through apertures of each terminal member are arranged spaced from each other and in a predetermined pattern. Also included is a plurality of pin structures, one pin structure for each pair of through apertures, where one pin structure is secured in the first through apertures of the respective first and second terminal members and another pin structure is secured in the second through apertures of the respective first and second terminal members. Such securing results in the first and second terminal members being maintained in fixed relation. Such a device is located within a housing so that the terminal portions extend outwardly from a housing end surface.

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.
