The Mersen X1048682 is a high-performance NH3L photovoltaic fuse-link engineered specifically for protecting high-voltage DC solar power systems. Part of the established Mersen HelioProtection® HP15NH series, it provides dependable full-range gPV protection for cables and equipment within photovoltaic string groups, combiner systems and inverter input circuits.
This specialist photovoltaic fuse is designed to interrupt the low-level fault currents and high short-circuit currents that can occur within solar arrays. Its robust construction withstands repeated current and temperature cycling, helping maintain reliable electrical protection and long-term system availability in demanding commercial and utility-scale installations.
With a rated current of 315 A, a voltage rating of 1500 V DC and a breaking capacity of 150 kA DC, the X1048682 is suitable for high-capacity photovoltaic applications. Its Size 3L body and DIN-type bolted blades allow secure direct mounting within compatible DC protection equipment.
Photovoltaic installations can generate sustained reverse currents and relatively low-level DC faults that conventional industrial fuse-links may not safely interrupt. A correctly selected gPV fuse isolates these abnormal currents before excessive electrical energy damages cables, combiner equipment, inverter inputs or other critical solar components.
The Mersen HP15NH range has been developed as main fuse protection for groups of photovoltaic strings. Its high breaking capacity, low fault-current interrupting capability and resistance to repeated thermal cycling make the X1048682 suitable for renewable energy installations requiring dependable long-term protection.
