A circuit breaker assembly includes a housing, an electrical bus structure coupled to the housing, and a number of first plug-in members coupled to the electrical bus structure. A number of circuit breakers include a first surface and a second plug-in member disposed opposite the first surface. The second plug-in member of each of the number of circuit breakers is mated with a corresponding one of the number of first plug-in members. A plate member is removably coupled to the housing. The plate member includes a first surface and an opposite second surface. The first surface of the number of circuit breakers engages the opposite second surface of the plate member in order to maintain mating of each of the number of circuit breakers with the corresponding one of the number of first plug-in members.
Abstract:
An electrical switch apparatus (1; 121, 121' ) includes a panel (127) having a first side (129) and an opposite second side (131), a housing (125) coupled to the opposite second side of the panel, separable contacts (17), an operating mechanism structured (19) to open and close the separable contacts, and a trip mechanism (21,27) cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a test circuit (115) structured to simulate a trip condition to trip open the separable contacts, and a proximity sensor (101; 123; 123' ) disposed on or within the housing proximate the opposite second side of the panel. The proximity sensor is structured to sense a target (133) to actuate the test circuit when the target is disposed proximate the first side of the panel and opposite the proximity sensor.
Abstract:
An aircraft circuit breaker includes a housing and a conductive member coupled thereto. The conductive member has a first conductive portion structured to be electrically and mechanically coupled to a conductive panel and a plurality of second conductive portions with a plurality of openings therethrough. An electronic circuit cooperates with an operating mechanism to trip open separable contacts. The circuit includes printed circuit boards having a plurality of conductive pads defining a ground. Each conductive pad has an opening therethrough. Each of a plurality of threaded conductive fasteners includes a conductive end portion, a conductive shaft disposed from the conductive end portion, and a plurality of conductive threads disposed on the conductive shaft. A number of the conductive threads electrically and mechanically engage a corresponding second conductive portion at a corresponding one of the openings. The conductive end portion electrically engages a corresponding one of the conductive pads.
Abstract:
A circuit breaker panel includes a number of circuit breaker modules each having a number of connectors, a plurality of circuit breakers and a circuit structure supporting the circuit breakers and electrically interconnecting the circuit breakers with the number of connectors. The panel also includes a monitoring module having a connector and a monitoring circuit to monitor at least one line voltage and, for each of the circuit breakers, at least one load voltage. The panel further includes a frame having a first connector for the monitoring module connector, a number of second connectors for the circuit breaker module connectors, and a number of third connectors for outputs from the circuit breaker modules. Conductors are connected to the connectors. Any of the monitoring module and the number of circuit breaker modules can be installed into or removed from the frame without change to the conductors.
