Mersen’s HP10J photovoltaic (PV) fuse series is designed specifically for DC Recombiner Boxes in the protection of 1000VDC photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated HP10J 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. Protect your off-grid or grid tied PV system from unexpected ground faults and line faults using Mersen’s HelioProtection® fuse line.
