Abstract: A thermally managed electromagnetic switching device (2) is provided that includes a current carrying component set (4) switchable between a closed, current carrying state and an open, current interrupting state. A thermally dissipating component set (6) functionally supports and electrically isolates the current carrying component set (4) in the open state. The thermally dissipating component set (6) includes at least in part a thermally conductive polymer and is cooperatively configured to transfer heat away from the current carrying component set (4) in the closed state to dissipate thermal energy.

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.

Abstract: 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.
