The NV strip type fuse-switch-disconnectors include three single-post connections in one unit. Each one contact at an individual stage is associated with the stage on the busbar framework. Alternate contacts are fitted with link interfacing terminals or for connection of the accompanying busbar framework. The switch-disconnectors are principally utilized for link dissemination and power supply frameworks, transformer frameworks, where they are joined when electric vitality transmission is needed. The accompanying appraised flows are accessible: 160 A, 250 A, 400 A, 630 A. Standard of operation The NV strip sort wire switch-disconnectors are utilized as a part of combo with NV wire cartridges ensuring the circuit against shorts. The upper a piece of the NV strip-type fuse-switch-disconnectors with insulation class IP3X is provided with a different test.
