The Mersen M1048673, catalogue reference HP12NH2LGPV200B, is a specialist 200 A photovoltaic fuse-link engineered to protect photovoltaic cables and DC equipment in commercial and utility-scale solar installations. As part of the proven Mersen HelioProtection® HP12NH series, it is specifically designed for photovoltaic systems operating at up to 1250 V DC.
Unlike conventional industrial fuses, the HP12NH series has been developed for photovoltaic applications where sustained reverse currents and unique DC fault conditions require dedicated protection. Its full-range gPV operating characteristic safely interrupts both low-level overcurrents and high-energy short-circuit faults, helping protect photovoltaic cables, combiner boxes and inverter DC inputs.
With a 200 A current rating, 1250 V DC operating voltage, 50 kA DC breaking capacity and direct-mount bolted blade terminals, the M1048673 delivers dependable overcurrent protection while simplifying installation in modern photovoltaic distribution systems.
Modern photovoltaic arrays require dedicated DC protection because solar circuits generate fault conditions that differ significantly from conventional AC systems. The Mersen HP12NH range has been engineered specifically to provide full-range protection against overloads and short-circuit faults within photovoltaic installations.
The M1048673 helps protect grouped photovoltaic cables and connected equipment by safely interrupting fault currents before damage can occur. Its direct-mount construction makes it particularly suitable for combiner boxes, inverter inputs and high-current DC distribution assemblies.
