The new photovoltaic fuse line provides overcurrent protection at the combiner box and inverter levels and covers applications ranging from 1 to 400A, 600VDC, and 1000VDC. The construction of the HelioProtection series 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.
