FERRULE MOUNTED FUSES

Mersen fuses for the protection of transformers and distribution lines

deliver overload and short circuit protection. These current-limiting

fuses will melt at current that can be as low as 1.7 times the fuse

current ratings up to its maximum interrupting rating. These fuses are

designed to withstand the transformer magnetizing inrush current.

They have 2 (size C), 3 (size D) and 4 (size E) inch diameter barrels

with ferrules and are mounted in spring reinforced clips.
