Cutout Fuse

Cutout fuse combines a fuse and switch. The unit allows transformer to disconnect from the power line in case of emergency. It consists of a fusible metal bar supported between two terminal clips by an insulator. If a short circuit occurs, the fusible metal bar will melt, protecting electronic devices form the overcurrent damage and operation errors of the inner electronic components. Cutout fuse has been widely used in power systems, electrical installations as well as domestic appliances. As a failsafe, its operational principle is simple and installation convenient.
