Isolating switch SPX-D 3P+N 250 A NH01 605111

Safe and Reliable Circuit Disconnection – Isolating Switch SPX-D

The SPX-D 3P+N 250A isolating switch is designed for the safe disconnection of electrical circuits, providing effective protection for installations and equipment. It is intended for use with NH01 fuse carriers and is an ideal solution for both industrial and commercial applications. The device’s design allows for circuit disconnection under load, enhancing safety during maintenance or repair operations.

Construction and Application

The SPX-D isolating switch features a robust construction and high manufacturing quality. It is mounted on a mounting plate, simplifying installation and ensuring stability. The switch is compatible with XL3 800 and XL3 4000 distribution board systems, guaranteeing seamless integration with widely used distribution panel architectures. It incorporates a dual visible break contact system with flicker switching, ensuring reliable and rapid circuit disconnection. Designed to protect against the effects of short circuits and overloads.

• Rated current 250A: Enables use in circuits with higher power demand.
• Four poles (3P+N): Provides full protection, including disconnection of the neutral conductor (though the neutral is not protected by fuses).
• Compatibility with NH01 fuses: Allows use of standard fuse carriers readily available on the market.
• Lockable operating lever: Enhances operational safety by preventing accidental re-energizing during maintenance (requires separate padlocks – not included in the set).
• Compliance with IEC 60947-3 standard: Confirms adherence to European safety and quality requirements.

Note: Fuse carriers, rotary actuators, and auxiliary contacts must be purchased separately – the switch is supplied without these components. This provides flexibility in tailoring the device to specific installation requirements. Device dimensions: width 329 mm, height 246 mm, depth 214 mm – these dimensions must be considered when planning the mounting space.
