Cylindrical fuse links for photovoltaic applications
gPV 14x51 cylindrical fuse links from DF Electric have been developed to offer a compact, safety and economic protection of photovoltaic modules (string protection) with voltages up to 1.000/1.100V DC.
The range comprises the following fuse links:
Size 14x51 1100V DC 15A and 20A
Size 14x51 1000V DC 25A and 32A
They provide protection against overloads as well as short-circuit (gPV class
according to the requirements of IEC60269-6 and UL248-19 Standards).
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 in silver plated copper 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 14x51 PMX-PV fuse
holders.
