Mersen HP10M2 HelioProtection gPV photovoltaic fuse rated at 2 A and 1000 V DC, with a compact 10.4 x 38.1 mm body and ferrule terminals for PV string protection.
£8.40
The Mersen HP10M2, reference number C1018580, is a compact gPV photovoltaic fuse link developed specifically to protect solar PV string circuits against ground faults, line faults and damaging overcurrents. As part of the proven Mersen HelioProtection® HP10M series, it is engineered for dependable operation in grid-connected and off-grid photovoltaic systems.
Rated at 2 A and 1000 V DC, the HP10M2 is designed to interrupt the relatively low fault currents commonly produced by photovoltaic arrays. Its minimum breaking-current capability of approximately 1.35 times the rated current supports safe circuit isolation under conditions where conventional industrial fuses may not provide suitable protection.
The HP10M2 features a compact 10.4 × 38.1 mm cylindrical body with tin-plated copper ferrule terminals for installation in compatible clip-mounted fuse holders. Its durable construction withstands continuous current and temperature cycling, helping improve system longevity in industrial rooftop, commercial and utility-scale solar installations.
Photovoltaic arrays can continue generating DC current whenever sufficient light is present, including during some electrical fault conditions. Specialist gPV fuses are therefore required to interrupt low-level reverse currents and short-circuit currents before they damage modules, cables, connectors or connected equipment.
The Mersen HP10M2 combines a low minimum breaking-current capability with a high interrupting rating, providing coordinated protection for low-current PV strings. Its robust design is suitable for the continuous thermal and electrical cycling experienced in outdoor renewable energy installations.
