Protect your off-grid or grid connected PV system from unexpected string faults using Mersen’s HelioProtection® fuse line
Developed specifically for the protection of PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated fuse is designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays.
The 10 X 38mm fuse can be used standalone with the DIN mount string fuse holder to fuse a single circuit or as a bank of fuses in a solar combiner box.
