The Mersen Y1037620, catalogue number HP10NH2GPV250, is a high-performance gPV photovoltaic fuse link developed specifically for protecting solar photovoltaic systems against damaging overcurrents and short circuits. Part of the Mersen HelioProtection® HP10NH series, this fuse provides dependable DC circuit protection for large-scale solar arrays, combiner equipment and inverter inputs.
Designed for operation at up to 1000 V DC, the Y1037620 carries a rated current of 250 A and uses an industry-standard NH2 fuse body. Its full-range gPV operating class enables the fuse to interrupt both low-level fault currents and severe short-circuit currents, helping protect photovoltaic cables, conductors and associated equipment.
The fuse is equipped with plain blade contacts for installation in compatible fuse clips. Its robust construction, low power losses and ability to withstand repeated temperature cycling make it suitable for demanding outdoor and industrial photovoltaic installations where long-term system reliability is essential.
Photovoltaic installations can generate continuous DC fault currents that require specialist protective devices. Standard industrial fuses may not reliably interrupt the low-level fault currents associated with solar arrays, which is why dedicated gPV fuse links are used.
The Mersen Y1037620 is designed to isolate faulty photovoltaic strings, cables and array sections before excessive current causes damage. Its full-range gPV performance supports dependable protection throughout the operating range of the fuse, while its low power dissipation helps minimise energy losses within the system.
