Drop Out Fuse Cutout Main Principle

Drop out fuse cutout and load switch fuses are high-voltage protection devices for outdoor use. The pipes are connected to the incoming line or distribution line of the distribution transformer, and mainly protect the transformer or line from short circuit, overload and on/off load. The drop fuse is composed of an insulating bracket and a fuse tube. The static contacts are fixed on both sides of the insulating bracket, and the moving contacts are installed at both ends of the fuse tube. The fuse tube is composed of internal arc extinguishing tubes. The outer layer of phenolic composite paper tube or epoxy glass tube, load switch fuse provides reinforced elastic auxiliary contacts and arc extinguishing shell switch on and off load current.

What is a Drop out fuse cutout ?

Drop Out fuses are protective devices that protect networks and equipment from current surges and overloads. The overcurrent will melt the fuse element in the carrier, thereby opening the line or device. They also provide a network isolation point when manually operated with a hot rod.

Where are Drop out fuse cutout used?

A drop (swing) fuse is a push-out type whose main function is to protect transformers on rural distribution networks. It is also especially useful for inaccessible substations that require fuse indication.

Application

Widely used in high and low voltage distribution system, control system and electrical equipment, as a short circuit and over current protector, is one of the most widely used protection devices;
