Abstract: Fuse assemblies in the form of fuse blocks and fuse holders include embedded permanent magnet arc suppression features that facilitate higher voltage operation of fusible circuit protection without increasing the size of the fuse assemblies. The embedded magnets apply an external magnetic field upon an overcurrent protection fuse and produce an arc deflection force to enhance arc quenching capability of the fuse without increasing its form factor.

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.
