The Mersen G1048668, catalogue reference HP10NH1GPV160B, is a high-performance gPV photovoltaic fuse link designed specifically for protecting solar photovoltaic circuits against dangerous overcurrents and short circuits. Part of the proven Mersen HelioProtection® HP10NH series, it provides dependable DC circuit protection for commercial, industrial and utility-scale solar installations.
Rated at 160 A and 1000 V DC, this NH1 fuse is engineered to interrupt the low-level and high-level fault currents that can occur within photovoltaic arrays. Its full-range gPV operating characteristic helps protect PV cables, combiner boxes, inverter inputs and associated DC equipment throughout the expected range of photovoltaic fault conditions.
The G1048668 features silver-plated copper DIN-type blades for secure direct mounting within compatible fuse bases and photovoltaic distribution equipment. Its compact NH1 body, high breaking capacity and resistance to repeated temperature cycling make it suitable for demanding solar installations where long-term reliability, low power losses and international standards compliance are essential.
Photovoltaic installations can continue generating current whenever sufficient light is present, making dependable DC overcurrent protection essential. A gPV fuse is designed to disconnect photovoltaic circuits safely when reverse currents, cable faults or short circuits exceed acceptable operating levels.
The Mersen G1048668 is particularly suited to the protection of grouped PV strings and main DC circuits. Its high breaking capacity helps isolate faults before they cause extensive damage to cables, combiner equipment, inverter inputs or other system components.
