The Mersen T1012017 is a compact, high-performance cylindrical photovoltaic fuse-link designed specifically to protect solar PV strings and arrays against reverse currents, ground faults and line faults. Part of the proven Mersen HelioProtection® DC10HEL series, it provides dependable gPV protection for grid-connected and off-grid photovoltaic systems.
This fuse features an enhanced internal construction developed to withstand the continuous temperature and current cycling commonly experienced in solar installations. Its low minimum breaking-current capability allows the fuse to interrupt the relatively low fault currents that can occur within photovoltaic arrays, helping protect modules, conductors, combiner equipment and inverter inputs.
With a rated current of 10 A, a voltage rating of 1200 V DC and a compact 10 × 85 mm cylindrical format, the T1012017 is suitable for installation in compatible fuse clips and holders. It is an effective protection solution for commercial, industrial and utility-scale solar energy systems.
Photovoltaic systems can produce sustained reverse currents and relatively low-level DC fault currents that conventional fuse-links may not safely interrupt. A correctly selected gPV fuse is designed to isolate these faults before excessive current damages photovoltaic modules, cabling, connectors or associated distribution equipment.
The Mersen DC10HEL series combines low fault-current interruption with durable construction and resistance to repeated thermal cycling. These characteristics make the T1012017 suitable for solar installations where reliable protection, long service life and consistent performance are essential.
