Description

Fuse isolator switch structure is simple, easy to install and disassemble. The base, handle, and arc extinguishing cover are made of arc-resistant plastic, which has good mechanical strength, flame retardancy and dielectric properties. The bar switch can be inserted into fuse body as a moving contact, or it can be directly used as a isolator switch with a blade.

Tips: Fuse isolator switch structure features.

Fuse isolator switch is mainly composed of base, handle, arc extinguishing cover and other parts.
Three sets of static contacts are directly installed on the base, and fuse body is installed in the handle to directly serve as moving contact blade.
Handle can be opened in a fan-shaped rotation along the fulcrum on base, so that the fuse can be completely pulled out of static contact. The handle can also be easily removed from the base to facilitate switch installation and safe installation/removal of the fuse.
