NH SPX3 630A fuse disconnect on 60mm busbar 605209

Safety and reliability in your installation – NH SPX3 630A fuse disconnect switch

This three-pole NH SPX3 fuse disconnect switch, designed to work with NH3 fuse links, is a key element ensuring effective protection of electrical circuits. Designed by Legrand, it combines a solid construction with functionality, meeting the needs of both professional installers and end users. Mounting on a 60mm busbar provides convenient and quick installation.

Construction and application

The SPX3 disconnect switch is characterized by high mechanical and thermal resistance. Its design allows for safe and convenient replacement of the fuse link, and the presence of a cover handle further increases user comfort. Designed for busbar mounting, it is ideal for electrical switchboards with a rated voltage of up to 800V AC. Thanks to the high continuous rated current (630A) and conditional short-circuit current (50kA), it is a solution dedicated to circuits with high load. As a main and safety disconnect switch, it provides comprehensive protection of the installation against overloads and short circuits.

Key features and benefits

• High short-circuit breaking capacity: Rated conditional short-circuit current of 50kA guarantees effective protection against the effects of sudden overvoltages.
• Versatility: Designed for use with NH3 fuse links, ensuring compatibility with a wide range of applications.
• Easy installation: Mounting on a 60mm busbar significantly speeds up the installation process and minimizes labor costs.
• Safety of use: The design with a cover handle makes it easier to replace the fuse link without the risk of electric shock.
• Solid construction: Made of high-quality materials, guaranteeing long-lasting and reliable operation of the device.
• Application as a safety disconnect switch: The additional function of a safety disconnect switch allows you to disconnect the circuit for maintenance or repair work.
• High working power: Rated working power for AC-23, 400 V is as high as 435.96 kW, making it an ideal solution for demanding industrial and commercial applications.
• IP40 protection class: Provides protection against access to hazardous live parts and against solid objects larger than 1mm.

This disconnect switch is not only a protective element – it is an investment in the safety and stability of your electrical installation.
