To be connected with incoming feeder of distribution transformer of distribution lines it mainly protect transformer or lines from short circuit and overload, and on/off loading current.
A D O Fuse (Drop Out Fuse) is one of the most essential protection devices used in high voltage (HT) distribution systems across India. It is designed to protect distribution transformers, overhead power lines, and electrical equipment from overloads, short circuits, and fault currents. When a fault occurs, the fuse element melts and the fuse carrier drops automatically, creating a visible break in the circuit that helps maintenance teams quickly identify and isolate the faulty section.
