Eaton Bussmann PV-20A10F 20 A gPV fuse

Eaton Bussmann PV-20A10F 20 A gPV Fuse

This Eaton Bussmann PV-20A10F is a cylindrical, fast-acting solar fuse rated at 20 A and 1 kV DC. It belongs to the PV-F series and carries a gPV class designation for photovoltaic circuit protection. The fuse features a ceramic body and a single-element design with a 33 kA interrupt rating at 1000 V DC. It meets CCC, CSA, IEC 60269-6, and UL 2579 standards.

Suitable for 20 A photovoltaic string protection

This fuse suits installers protecting 20 A photovoltaic strings or combiner boxes requiring gPV-class coordination. It is not for AC mains circuits, DC systems exceeding 1000 V, or applications needing visual or remote blow indication. Buyers who need a rejection-style fuse block or a higher ampacity rating should look at other devices.

Simple cylindrical installation in compatible

The 1-1/2 in by 13/32 in cylindrical body fits standard PV-F series fuse holders without special tools. Because the fuse is non-rejection, it will seat in any holder accepting those dimensions, so verify the holder voltage and interrupt rating match the 1000 V DC and 33 kA specifications. A common error is using an undersized holder that cannot safely clear the rated fault current.
