Reliable Protection for 1500 V Photovoltaic Systems
Photovoltaic installations can generate sustained reverse currents and relatively low-level DC faults that conventional industrial fuse-links may not safely interrupt. A correctly selected gPV fuse isolates these abnormal currents before excessive electrical energy damages cables, combiner equipment, inverter inputs or other critical solar components.
The Mersen HP15NH range has been developed as main fuse protection for groups of photovoltaic strings. Its high breaking capacity, low fault-current interrupting capability and resistance to repeated thermal cycling make the X1048682 suitable for renewable energy installations requiring dependable long-term protection.
Typical Applications
- Photovoltaic string group protection.
- Solar combiner and re-combiner boxes.
- Solar inverter DC input protection.
- Utility-scale photovoltaic farms.
- Commercial and industrial solar installations.
- High-voltage DC distribution systems.
