Why you should install a fuse cutout?

A fuse cutout is an electrical protection device utilized on overhead line systems to prevent distribution transformers from being damaged by power surges. These devices function by placing a fuse link in series with the transformer feed cables. The link passes through a hinged tubular fuse holder in such a way that it secures the fuse holder in position on the cutout body. Should the link melt and separate under overcurrent conditions, the fuse holder will drop free under its own weight, pivot down on the hinge and hang vertically, giving a clear visual indication of its status. Most fuse cutout designs also incorporate a metal ring on the fuse holder, which allows maintenance and repair personnel to manually disconnect the fuse should they be required to work on the transformer.
