Why Choose the Mersen X1008754 HelioProtection® Photovoltaic Fuse?
The Mersen X1008754 is a compact, high-performance cylindrical photovoltaic fuse-link designed specifically to protect solar PV strings and arrays against reverse currents, line faults and short circuits. Part of the proven Mersen HelioProtection® DC10HEL series, it provides dependable full-range gPV protection for high-voltage photovoltaic installations.
Its enhanced internal construction is engineered to withstand the continuous current and temperature cycling commonly experienced within solar power systems. The fuse is capable of safely interrupting relatively low photovoltaic fault currents, helping to protect modules, conductors, combiner equipment and inverter inputs throughout the service life of the installation.
With a rated current of 12.5 A, a voltage rating of 1200 V DC and a compact 10 × 85 mm cylindrical format, the X1008754 is suitable for installation in compatible photovoltaic fuse clips and holders. Its 12 kA DC breaking capacity makes it an effective protection solution for commercial, industrial and utility-scale solar energy systems.

Reliable Protection for Photovoltaic Strings and Arrays
Photovoltaic systems can generate sustained reverse currents and relatively low-level DC fault currents that conventional industrial fuse-links may not safely interrupt. A correctly selected gPV fuse isolates these abnormal currents before excessive heat or electrical energy damages photovoltaic modules, cables, 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 X1008754 suitable for photovoltaic installations where dependable protection, long service life and consistent electrical performance are essential.
Typical Applications
- Photovoltaic string and array protection.
- Solar combiner boxes.
- Solar inverter DC input circuits.
- Commercial rooftop photovoltaic systems.
- Utility-scale solar installations.
- Grid-connected and off-grid PV systems.
