ETEK 10 x 38 DC FUSE HOLDER
Solar PV Fuse DC Holder 1000V with High Voltage 15A/20A/25A/30A/32A PV Fuses for Solar System Protection
ETEK 10×38 Solar PV DC Fuse Holders are rugged mounting devices designed for high-voltage photovoltaic string protection in solar power systems. These holders accommodate standard 10 mm × 38 mm cylindrical PV fuses and provide reliable overcurrent and short-circuit protection in DC circuits up to 1000 V DC. Their secure clamping design ensures consistent electrical contact while allowing fast and safe fuse replacement. The holders install easily on DIN rail or panel and are ideal for solar combiner boxes, DC distribution panels, inverters, and battery storage protection.
They are compatible with photovoltaic string fuses specifically engineered for solar panel arrays. These 10×38 mm gPV fuses protect and isolate PV strings by interrupting both high fault currents and the low overcurrents typical of reverse currents or multi-array faults. They are widely used in solar panels, PV arrays, and DC string circuits.
