The Mersen DC10HEL photovoltaic (PV) fuse series is specifically designed to protect photovoltaic systems. Its improved fuse design makes it ideal for continuous temperature and current cycling, extending the life of the system. Rated at 1200 VDC and designed for a low minimum breaking capacity of 1.30 times the fuse's rated current, the DC10HEL enables safe circuit interruption under typical low fault current conditions generated by PV arrays. Protect your off-grid or on-grid PV system from unexpected ground and grid faults with the Mersen HelioProtection fuse line.
