gPV Cylindrical fuses for photovoltaic applications
PV fuse-links for photovoltaic installations from DF Electric have been developed to offer a compact, safety and economic protection solution in photovoltaic installations where, due to the increase of the power and technologic evolution, no-load voltages above 800V DC are reached.
Also meet the requirements for instruments (multimeters) and traction equipment auxiliary circuits. The range comprises 10x38 fuse-links with rated currents between 1A and 20A. Rated voltage is 600 V DC or 1000V DC (direct current). Provide protection against overloads as well as short-circuits. Made with ceramic tube with high withstand to internal pressure and thermal shock, that allows a high breaking capacity in a reduced physical space.
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. For these fuse-links we recommend the utilization of PMF 1000V fuse holders in single pole version (ref. 481033) or two-pole version (ref.481233).
gPV NH fuses for photovoltaic applications
NH1 gPV 1000V DC fuse-links for photovoltaic
installations have been developed to offer a compact, safety and economic protection solution in second level panels of photovoltaic installations. The range comprises NH1 fuse-links with rated currents from 25A up to 160A. Rated voltage is 1000V DC (direct current).
They provide protection against overloads as well as short-circuits (gpV class according to IEC 60269 Standard), 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 brass and melting
elements are made of pure silver in order to avoid the aging and thus keep unalterable the electric characteristics.
For these fuse-links we recommend the utilization of 1000V NH1 ST fuse bases.
