gPV NH 1000V DC fuse links
NH gPV fuse-links for photovoltaic installations from DF Electric have been developed to offer a safety protection solution in sub-array, array or inverter DC input of photovoltaic installations. They provide protection against overloads as well as short-circuits (gPV class according to IEC 60269 and UL248-19 Standards, with a minimum fusing current of 1,35·In. Made with ceramic body with high withstand to internal pressure and thermal shock. Contacts are made in silver plated copper or brass and melting elements are made in pure silver in order to avoid the aging and thus keep unalterable the electric characteristics.
For these fuse-links we recommend the utilization of 1000 VDC NH ST fuse bases.
Bolted blade contact type are specially designed for applications where can be mounted directly on busbars.
