Fuse-switch disconnector is designed for installing PVC-type fuse links (or similar in design) and protecting electrical circuits from short circuits and overloads. Fuse link: the part of the fuse containing the fusible element(s), intended for replacement after the fuse has tripped. If overload currents or short-circuit currents exceed the permissible values, the fuse link burns out and the indicator lamp lights up. Fuse-switch disconnectors are used to protect cable lines, domestic and industrial equipment.
