£145.56
The Mersen X1037619 is a high-performance NH2 photovoltaic fuse-link designed specifically to protect cables and electrical equipment in high-voltage solar power systems. Part of the proven Mersen HelioProtection® HP10NH series, it provides dependable full-range gPV protection for photovoltaic groups, combiner circuits and inverter inputs.
This fuse-link is engineered to withstand the repeated current and temperature cycling commonly experienced in photovoltaic installations. Its gPV characteristic enables reliable interruption of overloads, reverse currents and short-circuit faults, helping protect valuable solar modules, conductors and DC distribution equipment.
With a rated current of 200 A, a voltage rating of 1000 V DC and a maximum breaking capacity of 50 kA DC, the X1037619 is suitable for demanding commercial and utility-scale photovoltaic systems. Its NH2 body and plain blade terminals allow secure clip mounting within compatible fuse bases and fuse-switching equipment.
Photovoltaic installations can produce sustained reverse currents and low-level DC faults that conventional industrial fuse-links may not safely interrupt. A correctly selected gPV fuse isolates abnormal currents before excessive heat or electrical energy damages cables, combiner equipment, solar modules or inverter inputs.
The Mersen HP10NH range is designed as main fuse protection for groups of photovoltaic strings. Its full-range operating characteristic, high breaking capacity and resistance to repeated thermal cycling make the X1037619 suitable for solar installations requiring dependable long-term electrical protection.
