Switch Fuse Unit

A switch fuse unit, also known as a switch-fuse-disconnector, is an electrical device used in electrical distribution systems. It combines the functions of a switch (for isolating a circuit), a fuse (for overcurrent protection), and a disconnector (for ensuring the circuit is completely de-energized).

Switch fuse units are commonly used in industrial and commercial electrical distribution systems. They are found in distribution boards and electrical enclosures, and they are designed to be easy to operate and service. These units provide a convenient way to isolate circuits, protect against overcurrents, and ensure the safety of personnel working on electrical systems.
