Abstract: A circuit interrupter has first and second contacts that are actuatable relative to each other between a closed position wherein a power source and a load are in electrical communication and an open position wherein the power source and the load are not in electrical communication. An arc extinguisher is also provided for extinguishing an arc that develops in the vicinity of the contacts. An electromagnetic coil, when energized, generates a magnetic field that permeates an area where the arc develops, the magnetic field urging the arc toward the arc extinguisher regardless of a polarity of the contacts. An auxiliary switch is operably connected to the contacts, such that upon movement of the contacts relative to each other from the closed position toward the open position, the auxiliary switch is activated so as to energize a circuit feeding power to the electromagnetic coil, thereby generating the magnetic field.

Abstract: An assembly includes a circuit board having at least two conductor traces formed thereon, each of the conductor traces having at least one hole associated therewith, a circuit breaker having at least two conductive terminals, each of the conductive terminals having a screw-receiving threaded opening, the threaded openings being aligned with the holes formed in the circuit board, and a spacing bracket comprising a floor positioned between the circuit board and the circuit breaker when the circuit breaker is attached to the circuit board, the floor having at least two terminal receiving openings passing therethrough, the openings separated from one another by a barrier and being aligned with the threaded openings of the circuit breaker and the holes of the circuit board.

Abstract: A circuit breaker design allows for the circuit breaker to have an overall height (i.e., measured vertically along the circuit breaker's exposed outwardly-facing surface in the typical orientation of circuit breaker panels) that is slimmer than achievable with known typical configurations, while at the same time still providing robust power (e.g., voltage) handling and arc interruption capabilities. This is achieved, for example, by providing various components formed from polymer materials (which are generally less conductive of heat than metals), reinforced by metal members in certain areas, if needed, as well as a very particular configuration of a permanent magnet that is employed for enhanced arc quenching.

Abstract: A circuit interrupter adapted to be detachably connected to a rail system includes a housing having a notch disposed thereon adapted to receive a first leg of the rail system. An engagement member having a notch disposed therein adapted to receive a second leg of the rail system is slideably carried by the housing such that the notch in the engagement member is moveable in a first plane toward and away from the notch in the housing between an engaged position and a disengaged position. An actuation member is slideably carried by the housing and is moveable in a second plane, different than the first plane, between an actuated position and an unactuated position, movement of the actuation member in the second plane being translated into movement of the engagement member in the first plane.

Abstract: A circuit interrupting device includes line and load terminals and an interrupter electrically coupled therebetween, the interrupter having open and closed conditions. The device also includes a fault detector configured to detect a fault in an electrical signal in the load circuit. When such a fault is detected, the fault detector causes actuation of the interrupter to the open condition. A communication interface is adapted to receive a remote test command signal, and a processor generates, in response to receipt of the remote test command signal, a simulated fault in the load circuit, such that the fault detector attempts to cause actuation of the interrupter to the open condition. The processor determines whether or not the fault detector successfully caused actuation of the interrupter to the open condition in response to receipt of the remote test command signal, and if not, generates an alarm signal indicative of a malfunction.
