Features:

Application

The dropout (swing out) fuse is an expulsion type and its main function is to protect Transformers on rural distribution network. It is also particularly useful for inaccessible Sub-stations where indication of fusing is of advantage.

Construction

The Drop out fuse set has single pole construction and shall be suitable for Vertical mounting. Each pole consist of galvanized steel base, insulators of reputed make, copper alloy DO Top & Bottom contacts and fuse carrier’s top & bottom contacts, epoxy extruded fiber fuse carrier.
