NH strip-type fuse-switch-disconnectors


NH strip-type fuse-switch-disconnectors are three-pole fuse-switch-disconnectors in vertical version. They combine three single-pole fuse-switches longitudinally arranged in one unit. Each of the feeder terminals is directly connected to one phase of a 3-pole busbar system. The outgoing terminals are equipped with terminals for cable conductors.

NH strip-type fuse-switch-disconnectors conform to the requirements of public utilities and industrial companies for power distribution boards in networks, transformer substations, cable distribution cabinets as well as main distribution boards. NH strip-type fuse-switch-disconnectors having built-in current-transformers which are essential devices for efficient energy management. With built-in fuse monitoring function they ensure short reaction time even in decentralized power distribution systems.
