Fuse disconnect switch 400A, size 2, 3-pole mounting on Sasy 60i, Basic version with box terminals XNH2-S400-BT 183066

Fuse disconnect switch – reliable installation protection

This three-pole fuse disconnect switch with a rated current of 400A, designed to work with NH2 fuse links, is a solid solution for electrical installations requiring high reliability and safety. Mounted on 60i rails, in a Basic version with screw terminals, it provides convenient and efficient connection of wires. It is a component that will work well both in new installations and during the modernization of existing ones.

Design and application

The XNH2-S400-BT disconnect switch is designed for rail mounting, which simplifies its installation and integration with the distribution system. Its design allows connection of wires from both the top and bottom, providing flexibility during installation. The rated continuous current of 400A guarantees stable operation even under heavy load. The use of screw terminals ensures a secure and durable connection of wires. The device does not function as an emergency switch or a safety/main disconnect switch, focusing on the role of a reliable fuse disconnect switch.

Key features and benefits

• High short-circuit strength: The rated conditional short-circuit current Iq is as high as 120 kA (at 500V) or 100kA (at 690V), which provides effective protection against the effects of short circuits.
• Universal mounting: The possibility of mounting on 60mm rails and connecting wires from the top or bottom simplifies installation in various configurations.
• Suitable for NH2 fuse links: Compatibility with popular NH2 fuse links ensures easy replacement and availability of spare parts.
• Solid construction: Made of high-quality materials, it guarantees long-lasting and trouble-free operation.
• Rated operating voltage: The maximum rated operating voltage Ue AC is 690V, which allows use in a wide range of electrical installations.
• Screw terminals: Allow quick and secure mounting of wires of various thicknesses.
• Short-time current Icw: The rated withstand short-time current Icw is 3kA, which further increases safety.

This disconnect switch is an optimal choice for installers looking for a reliable component to protect electrical circuits and for end-users who value safety and stability of the electrical installation.
