The Drop Out Fuse is widely used in overhead distribution systems as a protective device. This Fuse cutout is designed to protect transformers from over-current and surge damage by connecting the fuse in series with the transformer feeder cable.
The connection is made through a hinged tubular fuse, fixing the fuse in position on the cut body. If the link melts and separates under over-current conditions, the fuse holder drops freely under its own weight, rotates to the hinge, and hangs vertically, making its status clearly visible. This Drop out fuse cutout provides clear visual indication for maintenance personnel.
A High voltage drop out fuse combines both fuse and switch functions, and is used in primary overhead feeder lines and taps to protect transformers from overloads and current surges. It is especially suitable as a Distribution transformer fuse cutout in 11–36kV systems.
The Polymer drop out fuse design offers enhanced insulation performance and long service life in harsh outdoor environments.
