The Mersen Y1048683, catalogue number HP15NH3LGPV350B, is a high-performance gPV photovoltaic fuse link engineered to protect high-power solar installations against damaging overcurrents and short circuits. As part of the Mersen HelioProtection® HP15NH series, it is designed for main circuit protection within photovoltaic arrays, combiner panels and inverter input systems.
With a rated current of 350 A and an operating voltage of up to 1500 V DC, this fuse is suitable for modern utility-scale and commercial photovoltaic systems. Its full-range gPV operating class enables reliable interruption of both low-level overcurrents and severe short-circuit currents that may occur within solar DC networks.
The Y1048683 uses a robust NH3L body with DIN-type bolted blades for direct mounting. A high DC breaking capacity of 150 kA at 1500 V DC provides dependable fault isolation, while compliance with IEC and UL photovoltaic fuse standards supports use in internationally specified solar projects.
Photovoltaic systems can produce continuous DC fault currents that differ significantly from faults within conventional AC installations. Dedicated gPV fuse links are engineered to interrupt these currents safely and isolate affected circuits before cables, panels or power conversion equipment sustain serious damage.
The Mersen Y1048683 is intended for main fuse protection within photovoltaic groups of strings. Its high voltage rating, full-range operating characteristics and substantial breaking capacity make it suitable for protecting high-power solar circuits where dependable isolation and long service life are essential.
