Drop Out Fuse
Drop Out Fuse
Description
A drop-out fuse is a type of fuse used in electrical distribution systems to protect overhead power lines and transformers. When a fault occurs, the fuse automatically disconnects the circuit, preventing damage to equipment and ensuring safety. It is designed for outdoor use and provides reliable protection in high-voltage applications.
