NH XL gPV fuse links 1500V DC
NH fuse links for photovoltaic applications
NH gPV 1500V DC fuse links for photovoltaic installations have been developed to offer a safety protection solution in sub-array, array or inverter DC input of photovoltaic installations. The range comprises NH1XL, NH2XL and NH3L fuse links with rated currents between 40A and 400A. Rated voltage is 1500V DC (direct current).
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 of silver plated copper and melting elements are made of pure silver in order to avoid the aging and thus keep unalterable the electric characteristics. They have a low power losses values to get a good efficiency.
For these fuse links we recommend the utilization of 1500V DC NH XL fuse bases.
Bolted blade contact type are specially designed for applications where can be mounted directly on busbars.
