Fuse disconnect switch 400A, size 2, 3-pole plate mounting, Basic version with box terminals XNH2-A400-BT 183058

400A Fuse Disconnector – reliable installation protection

This three-pole fuse disconnector, designed to work with NH2 fuse links, is a solid solution for installations requiring high reliability and safety. Plate mounting facilitates integration with existing infrastructure, and the Basic version with screw terminals ensures convenient and secure connection of wires. The device is characterized by high short-circuit strength, reaching 120kA at 500V or 100kA at 690V, which guarantees effective protection against the effects of overloads and short circuits.

Key features and application

The XNH2-A400-BT disconnector is designed to operate in installations with a voltage of up to 690V AC and a continuous rated current of 400A. Its construction allows for mounting of wires entering from both the top and the bottom, which increases installation flexibility. Screw terminals ensure quick and secure wire mounting. The device is used in power distribution boards, control cabinets and other electrical installations requiring reliable protection against overloads and short circuits. It is an ideal choice for both professional installers and end-users looking for a proven solution.
