PV Fuses Protection

PV String Fuses and Fuse Holders (gPV)

gPV fuses are purpose-designed for photovoltaic strings and combiner boxes, clearing DC faults at 1000–1500 V DC where ordinary fuses would sustain an arc. We stock Mersen HelioProtection 10 × 38, 10 × 85, 14 × 51 and NH-size gPV fuses and holders, with Woehner NH fuse bases rated to 1500 V DC and Lovato Electric PV fuse holders.

Filter by voltage rating, current and body size. For AC and semiconductor fuses see Fuse Protection; for string isolation see PV switch disconnectors.
