Reliable Protection for Photovoltaic Power Systems
Photovoltaic installations require specialised DC fuses because solar arrays can continue feeding fault current whenever sufficient light is available. A correctly specified gPV fuse disconnects the affected circuit before excessive current damages PV cables, modules, combiner equipment or inverter components.
The Mersen HP10NH1GPV125 provides full-range photovoltaic protection with a high DC breaking capacity and durable NH construction. Its electrical performance makes it suitable for demanding solar installations where system availability, equipment protection and safe fault isolation are essential.
Typical Applications
- Photovoltaic grouped string protection.
- Solar array combiner boxes.
- Main PV fuse applications.
- Inverter DC input protection.
- Commercial rooftop solar systems.
- Utility-scale photovoltaic power plants.
