Cylindrical gPV-class fuses rated at 1500 V DC are designed to protect high-voltage DC photovoltaic (PV) circuits. They operate effectively under both prolonged overloads and short-circuit currents, providing reliable protection for stringers, combiner boxes, cable lines, and inverter inputs. The CH 10×85, CH 10/14×85, and CH 10/14×85 T models are designed to meet the requirements of high-voltage PV systems and comply with international safety standards.
Advantages
- High operating voltage — up to 1500 V DC, allowing the fuses to be used in modern high-voltage solar installations.
- gPV class — full range of PV protection (from overload to short circuit).
- Compatibility with EFH CH 10×85, CH 10/14×85, and CH 10/14×85 T — can be mounted in standard DIN-rail systems.
- T (touch safe) version — enhanced maintenance safety, enclosed contact assembly.
- Compliance with standards — IEC 60269-6, UL 248-19 for select models.
