Isolating switch SPX-D 3P+N 630 A NH03 605113

Isolating Switch-Fuse – Reliable Disconnection and Installation Protection

The isolating switch SPX-D 3P+N 630A NH03 is a critical component ensuring safe and effective disconnection of electrical circuits. Designed to work with NH03 fuses, it guarantees effective protection against overloads and short circuits, while enabling safe maintenance and repairs. The device’s design allows visual verification of circuit status – assurance that isolation is maintained.

Construction and Application

This isolating switch is a robust solution for high-load installations requiring high reliability and safety. The panel-mount design ensures stability and seamless integration with existing systems. The device is designed for use in electrical distribution boards, control cabinets, and other locations where visible and secure circuit disconnection is required. Rated for a nominal current of 630A, it performs excellently in industrial, commercial, and public utility buildings.

Key Features and Benefits

• High Short-Circuit Withstand Capability: Rated conditional short-circuit current (Iq) of up to 100 kA ensures effective protection of the installation during fault conditions.
• Designed for NH03 Fuses: Compatibility with NH03 fuses guarantees proper selectivity and protection coordination.
• Four Poles (3P+N): Enables disconnection of all phases and the protective neutral conductor, enhancing safety during maintenance work.
• Robust Construction: Manufactured from high-quality materials, ensuring long-term, reliable operation even under harsh environmental conditions.
• Panel Mount Installation: Simplifies integration with existing distribution systems and minimizes installation time.
• Protection Rating IP40: Protects against accidental contact and ingress of solid objects larger than 1 mm.
• Dimensions: Width 426 mm, height 317 mm, depth 314 mm – allows flexible integration into various distribution board configurations.
• With Cover: Additional protection against accidental contact with live parts.

The switch has a rated current of 630A and a short-circuit breaking capacity of 100 kA. It is designed for use with NH03 fuses and features four poles (3P+N). Installation is performed on a mounting panel, and the IP40 protection rating provides basic defense against external elements. Dimensions are 426 mm (width) × 317 mm (height) × 314 mm (depth).

The SPX-D isolating switch is an investment in the safety and reliability of your electrical installation – for both professional installers and end-users benefiting from a protected facility.
