£168.66
The Mersen D1025389 is a high-performance gPV photovoltaic fuse-link designed to protect solar power circuits against overloads and short circuits. Rated at 63 A and 1200 V DC, it provides dependable protection for photovoltaic arrays, combiner boxes, inverter inputs and associated DC distribution equipment.
This fuse features a robust square-body NH120 construction developed for the demanding electrical and thermal conditions found in photovoltaic installations. Its gPV operating characteristic provides full-range protection for solar modules and connecting cables, helping to minimise equipment damage and unplanned system downtime.
With its high DC voltage capability, plain-blade terminals and purpose-designed photovoltaic performance, the Mersen D1025389 is suitable for commercial, industrial and utility-scale solar installations requiring reliable high-voltage circuit protection.
Photovoltaic systems can produce sustained DC fault currents that require protection devices specifically designed for solar applications. A gPV fuse-link disconnects a faulty circuit before excessive current can damage photovoltaic modules, cables, combiner equipment or inverter components.
The Mersen D1025389 combines a high DC voltage rating with a purpose-designed photovoltaic operating characteristic. This makes it suitable for protecting modern solar installations where dependable fault interruption, low system downtime and long-term electrical safety are essential.
