Mersen D1028287 HP10NH1GPV125 NH1 gPV photovoltaic fuse-link rated at 125 A and 1000 V DC with plain blades, clip mounting and a 50 kA DC breaking capacity.
£108.30
The Mersen D1028287 is a high-performance NH1 gPV photovoltaic fuse-link developed specifically to protect solar power circuits against overloads and short circuits. Part of the trusted Mersen HelioProtection® HP10NH series, it is designed for reliable protection of photovoltaic cables, grouped PV strings, combiner boxes and inverter input circuits.
Rated at 125 A and 1000 V DC, the HP10NH1GPV125 provides dependable full-range fault protection in demanding commercial and utility-scale solar installations. Its high breaking capacity enables safe interruption of substantial DC fault currents, while the gPV operating characteristic is optimised for the electrical behaviour of photovoltaic systems.
The fuse features a robust NH1 body, silver-plated copper plain blades and clip mounting for installation in compatible photovoltaic fuse bases. Compliance with IEC and UL photovoltaic fuse standards makes the Mersen D1028287 suitable for internationally specified renewable energy projects.
Photovoltaic installations require specialised DC fuses because solar arrays can continue feeding fault current whenever sufficient light is available. A correctly specified gPV fuse disconnects the affected circuit before excessive current damages PV cables, modules, combiner equipment or inverter components.
The Mersen HP10NH1GPV125 provides full-range photovoltaic protection with a high DC breaking capacity and durable NH construction. Its electrical performance makes it suitable for demanding solar installations where system availability, equipment protection and safe fault isolation are essential.
