Mersen's HelioProtection series is designed to protect photovoltaic strings

Mersen’s HelioProtection HP10M and HP15M photovoltaic (PV) fuse series are engineered and designed specifically for the protection of photovoltaic strings. Their enhanced fuse construction is designed to withstand constant fluctuations in temperature and current cycling adding to system longevity. Low minimum breaking capacity of 1.35 times the fuse rated current value meets both IEC and UL standards, allowing for safe circuit interruption under typical low fault current conditions produced by PV strings. Mersen’s crimp cap termination for HP10M and HP15M fuses enables users to attach wires directly to the fuses.
