摘要： A fusible disconnect switch devices includes dual sets of switch contacts to connect or disconnect a current path through an overcurrent protection fuse with reduced arcing severity. Faster acting and longer contact path switch mechanisms are described providing satisfactory switching of DC circuits without excessive electrical arcing in a reduced physical package size.

摘要： A compact disconnect device includes a magnetic arc deflection assembly including at least one set of stacked arc plates and at least one magnet disposed adjacent switchable contacts and establishing a magnetic field across the stacked arc plates. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC voltage circuitry well above 125 VDC with reduced arcing intensity and duration. The disconnect device may be a compact fusible disconnect switch device having dual sets of switch contacts in the same current path.
