Abstract: A power device can include a first conductive terminal, a second conductive terminal, a power overlay having a conductive backplane and solid state switches, and a controller module configured to selectively operate the solid state switches to enable conductive communication between the first conductive terminal and the second conductive terminal.

Abstract: A circuit breaker or conductor severing assembly can include a housing with a conductor extending through the housing. A piston disposed within the interior of the housing can be actuable within the housing between a first position and a second position, driven by a volume expansion composition. The piston can include a cutter, such that actuation to the second position can sever the conductor extending through the housing.

Abstract: A sealed feedthrough connector can include a non-conductive clamp plate having at least one first conductor aperture and further including at least one conductor having a first end connecting to electronics in a high-power electronics chassis. The conductor can include a second end connecting to a circuit external to the electronics chassis, with a shoulder between the first and second ends. The connector can include a non-conductive terminal panel, a plate seal, and a conductor seal, the terminal panel having at least one second conductor aperture. The non-conductive clamp plate can be secured to the non-conductive terminal panel with a wall of the electronics chassis and the plate seal between them. At least one conductor can extend the first end through the first conductor aperture and the second end through the second conductor aperture, the conductor seal being positioned between the shoulder and the clamp plate or the terminal panel.
