A compact fusible disconnect switch device includes a magnetic arc deflection assembly including pairs of magnets disposed about a mechanical switch contact assembly. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC circuitry operating at a voltage well above 125 VDC with reduced arcing intensity and duration. The pairs of magnets may apply magnetic fields in directions opposing one another to deflect electrical arcs in different directions at different locations in the mechanical switch contact assembly to facilitate high voltage DC switching operation.

A fused disconnect switch device includes a housing defining an interior volume, and a current path. An arc interruption assembly is located in the interior volume and includes a shell, and a conductor in electrical communication with the current path. At least one arc plate is located between the magnets and the conductor. The magnets cooperate to generate a magnetic field facilitating an interruption of a first arc between the conductor and the first side of the arc chamber and a second arc between the conductor and the second side of the arc chamber.

A panel fuse module for use with one or more fuses. The panel fuse module includes a housing with a first fuse contact and a second fuse contact. The first fuse contact is resiliently deformable and is mounted on a post of the housing. A movable fuse holder is provided which is moveable relative to the housing and relative to the first fuse contact. A cam member is provided on the movable fuse holder. As the movable fuse holder is moved from the first position toward the second position, the cam member cooperates with the first fuse contact to move the first fuse contact from a less-stressed first position to a more-stressed second position to allow the respective fuse of the one or more fuses to be inserted into the housing without engaging the first fuse contact.

A switching and protection device for high-voltage onboard electrical systems having a DC-voltage switch and a fuse, wherein the DC-voltage switch includes a housing, at least two fixed contacts, and a bridge designed to be movable with respect to the fixed contacts, wherein the bridge is formed from an electric insulator, wherein two contacts are arranged on the bridge such that, during a movement of the bridge in the direction of the fixed contacts, the two contacts make contact with the fixed contacts, wherein the two contacts arranged on the bridge are electrically connected to each other via the fuse.
