A matrix assembly is provided for an electrical system such as, for example, a power distribution unit for an aircraft. The electrical system includes an enclosure and a number of current carrying components such as, for example, electrical bus members, electrical switching apparatus, and/or fuses. The matrix assembly includes a matrix member having a generally planar portion, a plurality of attachment points for attaching the current carrying components to the generally planar portion, and a plurality of mounting points for attaching the generally planar portion to a thermally conductive structure such as, for example, an aluminum airframe structure. The matrix member is a thermally conductive liquid crystalline polymer. In addition to providing dielectric insulation, the matrix member also effectively transfers heat away from the current carrying components to the aluminum airframe structure, thereby reducing the temperature and corresponding electrical resistance within the electrical system and improving performance.

Electrical system and matrix assembly therefor

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

Thermally managed electromagnetic switching device

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.
