Fuse-switch disconnector PR 22x58 3P EKF pr-22-58-3

The fuse-switch disconnector is designed for the installation of fuse links and the protection of electrical circuits from short circuits and overloads. Fuse link: a part of a fuse containing a fusible element (elements), intended for replacement after the fuse trips. 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 comply with GOST IEC 60947-3-2016. They are used for the protection of cable lines, household and industrial equipment. Used in distribution panels ShO-70, input-distribution devices VRU, and power distribution cabinets ShRS.
