The ABB HTSS242050 is a back-up current-limiting fuse for distribution transformers, rated 17.2 kV and 50 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.
The same rating without the CN suffix is manufactured outside China.
