Cylindrical gPV-class fuses are designed for the full range of protection for photovoltaic (PV) DC circuits: from minor overloads to short-circuit currents. They provide fast and reliable protection for conductors, connections, strings, combiner boxes, and inverters in systems with operating voltages up to 1000 V DC. The CH gPV series is available in sizes 10×38 and 14×51, ensuring compatibility with most standard mounts and modular panels.
Advantages
- Full PV protection (gPV) – operation during overloads and short circuits with high efficiency.
- High rated voltage – up to 1000 V DC, suitable for modern solar installations.
- Compatibility with EFH DC enclosures – size 10×38 fits in EFH 10 DC, and 14×51 fits in EFH 14 DC.
- Safe maintenance – quick replacement without touching live parts.
- Compliance with standards – IEC 60269-6 (PV), UL for certain models.
