The Mersen Z1028283, catalogue number HP10NH1GPV50, is a high-performance gPV photovoltaic fuse link designed specifically to protect solar power systems against damaging overcurrents and short circuits. Part of the Mersen HelioProtection® HP10NH series, it provides dependable main-circuit protection for photovoltaic cables, grouped strings, combiner equipment and inverter input circuits.
Rated at 50 A and 1000 V DC, the Z1028283 is suitable for commercial, industrial and utility-scale photovoltaic installations. Its full-range gPV operating characteristic enables the fuse to interrupt the low-level fault currents associated with solar arrays as well as more severe short-circuit currents.
The fuse uses an internationally recognised NH1 body with plain silver-plated copper blades for installation in compatible fuse clips. A maximum breaking capacity of 50 kA at 1000 V DC, combined with low power dissipation and robust construction, supports reliable long-term operation in demanding renewable energy systems.
Photovoltaic arrays can generate persistent DC fault currents that require protective devices specifically engineered for solar applications. Conventional industrial fuses may not safely interrupt the comparatively low fault currents produced by photovoltaic modules under certain fault conditions.
The Mersen Z1028283 provides reliable isolation of faulty grouped strings and associated cables before excessive current damages modules, conductors, combiner equipment or inverter components. Its gPV characteristic, high breaking capacity and temperature-resistant construction make it suitable for long-term use in demanding solar energy installations.
