Description

An arc shorting rod is a copper rod that is attached to the fuse holder cap. This extension lowers the fuse link within the fuse tube making it possible to achieve higher interrupt ratings.

By using a copper arc shortening rod inside the top of the fusetube, higher interrupt ratings are obtainable. An arc shortening rod is attached to the cap of some fusetubes and lowers the fuse link within the fusetube. This permits a much shorter arc, resulting in less arc energy, and higher interrupting capacities. For 200 A tubes,it allows for full voltage ratings.
It is necessary to use fuse links with removable buttonheads when arc shortening rods are employed.
