Why Choose the Mersen V1069104 HelioProtection® Photovoltaic Fuse?
The Mersen V1069104 is a high-performance NH1 photovoltaic fuse-link engineered to protect cables, inverter circuits and electrical equipment used in solar power systems. Part of the specialist Mersen HelioProtection® NH 800 V AC gR range, it provides full-range protection against overloads and short-circuit currents.
Unlike partial-range semiconductor fuses, the V1069104 has a gR operating characteristic, allowing it to interrupt fault currents from relatively low overload levels through to its maximum breaking capacity. This enables the fuse-link to provide standalone protection for appropriately designed photovoltaic inverter circuits and associated AC equipment.
With a rated current of 100 A, a voltage rating of 800 V AC and an IEC NH1 body size, the V1069104 is particularly suitable for the AC side of high-power solar inverters. Its plain blade contacts allow straightforward clip mounting within compatible fuse bases and fuse-switch-disconnectors.

Reliable Protection for 800 V AC Solar Inverters
High-power photovoltaic inverters require carefully coordinated fuse protection to isolate abnormal currents before cables, semiconductor components and distribution equipment are damaged. Full-range gR fuse-links are designed to interrupt both overload currents and high-level short circuits, providing comprehensive protection within correctly engineered electrical systems.
The Mersen V1069104 is designed for use with DC-to-800 V AC solar inverters and may be combined with compatible Mersen fuse-switch-disconnectors to create a coordinated protection and isolation system. Its NH construction provides the mechanical durability required for industrial and renewable energy installations.
Typical Applications
- Photovoltaic inverter AC output protection.
- Commercial and utility-scale solar installations.
- 800 V AC renewable energy distribution systems.
- Solar inverter cables and equipment protection.
- Photovoltaic switchboards and control panels.
- Compatible fuse-switch-disconnector assemblies.
