Introduction to Dropout Fuse
A dropout fuse is a type of over - current protection device commonly used in electrical distribution systems. It is designed to protect electrical equipment and circuits from damage caused by excessive current. When an over - current condition occurs, such as a short - circuit or overload, the fuse element inside the dropout fuse melts, causing the fuse tube to drop out of its holder. This action visibly indicates that a fault has occurred and at the same time isolates the faulty section of the circuit from the rest of the system. Dropout fuses are widely used in overhead power lines, transformers, and other electrical installations due to their simplicity, reliability, and cost - effectiveness.
