1000v dc fuses | KYPV-H3 gPV Fuse Link (Square-Body, 315–500A)
Square-body 1000v dc fuses (gPV), H3 frame, 315–500A current range.
High breaking capacity 50 kA DC; ceramic body, silver fuse element, quartz-sand arc quenching.
Complies with IEC 60269-6 / UL 248-19; fits KYPV-H3B fuse holder.
Overview
The KYPV-H3 is a square-body 1000v dc fuse designed for high-current
PV combiner box mains, ESS DC busbars, and inverter input circuits. With a current range of
315–500A, this gPV fuse link offers safe interruption of DC overloads and short circuits.
Constructed with a ceramic body, silver fuse element, and quartz-sand filling, it achieves a
breaking capacity up to 50 kA. Use with the
KYPV-H3B fuse holder for secure installation.
