Drop Out Fuse

A Drop-Out Fuse Cutout is an outdoor high-voltage protective device primarily used on the high-voltage side of distribution transformers or branch lines. It provides overload and short-circuit protection and enables safe load current switching for transformers and lines.

The fuse cutout consists of an insulating base, a fixed contact, a moving contact, and a fuse tube. When a fault occurs, the fuse blows and drops out of the circuit, ensuring that the transformer or line remains protected.

These fuses are designed for reliable outdoor operation, handling high voltages and extreme weather conditions.
