Abstract: An electricity supply assembly comprises a circuit breaker comprising a housing (2) having generally flat, parallel side faces provided on the underside with a mounting recess (4), for mounting on a mounting rail of the conventional "top hat" section, comprising a base (7), spaced parallel flanges (8) extending from the base, and parallel outwardly extending flanges (9) which together provide a support surface which may be engaged by an underside of the recess (4). Extending from the underside of the circuit breaker at right angles to the plane of the base is a contact member (22). A supply assembly (28) comprises an elongate housing (30) within which an elongate bus-bar (32) is located, the bus-bar being provided with spaced intervals with spring clips (34). The housing (30) comprises a cover (36), provided at spaced intervals, corresponding to the spacing between the spring clips (34), with apertures (38).

Abstract: A modular electrical-energy distribution system has at least one conductor and a contacting device which makes it possible to establish, at essentially any point in the conductor system, a contact with the conductor. The tap or contacting devices essentially clamp onto or between conductor bars and therefore essentially permit all contacts to be made simply from one side of the conductor bars thereby reducing installation time.

Abstract: A circuit breaker has a line terminal comprising a pair of vertically spaced resilient terminal strips which extend in the transverse horizontal direction out from the breaker's housing to free ends of the strips, and which strips have formed therein near those ends respective bends disposed opposite each other and vertically projecting away from each other to bound opposite sides of a circular cylindrical cavity defined between those strips. A horizontal rail for conducting current is aligned in its lengthwise direction normal to those strips, and the rail has a flange received in the cavity in electromechanical contact with the strips, and also, a web extending in the transverse horizontal direction from the front flange out beyond the terminal to a rear flange for the rail. The shape, size and mass of the rail promote reduction of the temperature generated at the line terminal by the inrush of current carried by the rail in the presence of a short circuit in the load served by the breaker.

Abstract: An outlet housing includes a plurality of electrical outlets directed through a front wall thereof in electrical communication with a plug member mounted to a rear wall of the housing. A first selector switch is arranged to control electrical communication of the electrical plug with the outlets when below a predetermined temperature, or selectively above that predetermined temperature. A second selector switch is arranged to effect selective bypassing of a control circuit to effect direct electrical communication of the electrical plug with the electrical outlets bypassing a thermostatically controlled control circuit.

Abstract: A plug-in power supply includes a housing dimensioned to fit into a space designed to accept a circuit breaker in a load center to provide D.C. power from an A.C. main power. The housing encloses a circuit card that has components that are connected between A.C. inlet terminals and D.C. output terminals to provide a peak current for a short duration, limit the output to a D.C. voltage maximum, and interrupt the output current when the output voltage drops below a certain level.
