Fuse Switch Unit

A fuse switch unit (FSU) is an electrical device that combines the functions of a switch and a fuse in a single unit. It is commonly used in electrical distribution systems to provide circuit isolation and overcurrent protection.

Fuse switch units are often used in industrial and commercial applications, particularly in electrical distribution panels and switchgear. They provide a convenient way to isolate a circuit for safety or maintenance purposes while also offering the essential protection against overcurrents. When a fuse blows in a fuse switch unit, it can be easily replaced, making it a cost-effective solution for protecting electrical circuits.
