NH SPX 1 250 A 60 mm fuse disconnector 605205

Fuse disconnect switch – reliable installation protection

The NH SPX fuse disconnect switch is a key element of any electrical installation, providing effective protection against overloads and short circuits. Designed to work with NH1 type fuse links, this model offers high reliability and safety of use. The design allows mounting on a 60 mm busbar system, which facilitates integration with existing infrastructure.

Functionality and technical parameters

The device is characterized by a continuous rated current of 250 A and a short-circuit breaking capacity of up to 50 kA. The three-pole design provides comprehensive circuit protection. The rated operating power for AC-23 at 400 V is 173 kW, making it a suitable solution for demanding industrial and commercial applications. The maximum operating AC voltage is 800 V.

Mounting on a TH35 (60mm) rail is simple and intuitive, and the solid construction guarantees stability and long-term operation. The cover handle as an actuator provides convenient operation, and the ability to use it as a main or safety disconnect switch increases its versatility. The IP40 protection class protects against the ingress of solid objects larger than 1 mm, which is important in industrial environments.

For installers and end users

This disconnect switch is not only a protective element, but also a convenient tool for disconnecting the load during maintenance or repair work. Solid frame terminals ensure a secure connection of the wires, minimizing the risk of loosening connections during operation. Thanks to this, both installers and end users can count on trouble-free operation of the device for a long time. The design of the disconnect switch allows for easy visual inspection of the fuse link status (although the device does not have a built-in status control).
