Why Choose the ABB E9F8PV E 9F8 PV Fuse?
The ABB E9F8PV (E 9F8 PV) is a compact gPV cylindrical fuse link specifically designed for overcurrent protection in direct-current photovoltaic installations. Part of the ABB E 9F PV photovoltaic fuse range, it is engineered to protect PV strings, inverters and surge protection devices against damaging fault currents.
With a rated current of 8 A and a rated voltage of 1000 V DC, the E 9F8 PV is suitable for high-voltage solar DC circuits. Its standard 10.3 × 38 mm cylindrical format enables installation in compatible photovoltaic fuseholders, including ABB E 90 PV devices.
The E 9F PV range is designed specifically for photovoltaic applications in accordance with IEC 60269-6. The E9F8PV provides a 10 kA breaking capacity and, for the 8–30 A models in this series, a minimum breaking capability of 2.0 × In, providing dedicated protection for modern solar generation systems.
