Mersen's HP10J HelioProtection Fuse
HP10J photovoltaic fuse line provides superior overcurrent protection at the re-combiner box and inverter levels. It covers applications ranging from 70A to 400A, 1000VDC. The HelioProtection Series' enhanced fuse construction makes it ideal for continuous temperature and current cycling withstand, adding to system longevity. 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.
