● Contact for Availability

ABB HTSS372080 backup current-limiting fuse, 38.0 kV, 80 A, 50.0 kA interrupting, 83.5-85 x 490-492.8 mm, back-up type for distribution transformers, manufactured outside China.

Rated Current80 A
Rated Voltage38.0 kV
Breaking Capacity50.0 kA
Package83.5-85 mm dia. x 490-492.8 mm overall length (464-464.8 mm body)

The ABB HTSS372080 is a back-up current-limiting fuse for distribution transformers, rated 38.0 kV and 80 A. It is applied in series with a properly sized under-oil expulsion fuse (bay-o-net, load-sensing link or weak link): the expulsion fuse clears low-magnitude faults while the current-limiting fuse interrupts high fault currents and limits the let-through energy below the withstand capability of the transformer tank.
