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