The new HP10J photovoltaic fuse line provides superior overcurrent protection at the re-combiner box and inverter levels and covers applications ranging from 70A to 400A, 1000VDC. The enhanced fuse construction of the HelioProtection series makes it suited 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. Protect off-grid or grid-tied PV systems from unexpected ground faults and line faults using the HelioProtection fuse line. Primary customers for this fuse are solar array combiner box builders, solar inverter manufacturers, and solar installers and integrators.
