Rittal SV NH slimline fuse-switch disconnector 690 V, RAL 7035/7016/7001

Rittal SV NH slimline fuse-switch disconnector is a compact Abschaltblock designed for installation in switchgear and distribution panels. Intended for NH fuses, this device provides manual disconnection and accepts fuses for overcurrent protection in industrial and commercial electrical systems. It is rated for up to 690 V and is available in three standard enclosure colors (RAL 7035, RAL 7016 and RAL 7001) to match existing equipment layouts.

Advantages

The slimline geometry saves panel space while maintaining rated performance for NH fuses and manual switching. The unit supports reliable disconnection under load and provides a clear mechanical separation point for maintenance. Constructed to integrate into typical distribution and switchgear arrangements, it simplifies wiring and reduces installation time by offering a ready-made fuse accommodation and switch assembly.

Suitable for

• Installation in low- and medium-voltage distribution boards and switchgear
• Use with NH cartridge fuses for overcurrent protection up to the device voltage rating
• Commercial and industrial electrical panels where space-saving fuse-switch combinations are required

When it may not be suitable

This slimline fuse-switch disconnector is designed specifically for NH fuse systems and manual operation. It may not be suitable where remote or automatic tripping, electronic protection functions, or integrated monitoring of fuse condition are required. Also avoid using it outside its electrical ratings or in enclosures that do not provide the required clearances and mechanical support.

Key specifications

• Rated voltage: up to 690 V
• Compatible fuse type: NH cartridge fuses
• Design: slimline Abschaltblock for panel mounting
• Available colours: RAL 7035, RAL 7016, RAL 7001
• Operation: manual fuse-switch disconnector

How to use

Mount the Rittal SV NH slimline fuse-switch disconnector into the prepared cut-out or mounting position within the switchgear or distribution panel following the panel manufacturer’s instructions. Fit the appropriate NH cartridge fuse for the intended protection level, verify correct terminal connections and tighten connection bolts to the specified torque. Use the manual operating handle to open the unit before performing any maintenance; ensure that supply is isolated and that proper lockout/tagout procedures are in place. After replacement or inspection, close the switch and restore supply according to site safety protocols.

What to consider before purchase

• Confirm compatibility with the NH fuse size and class required for your protection scheme
• Verify the system voltage and current ratings to ensure they fall within the device limits
• Consider required mounting space and the color option to match existing panels

Usage recommendations

Use only NH cartridge fuses with the correct size and characteristic for the application, and perform electrical isolation and verification before any work. Regularly inspect terminal connections for tightness and signs of heating. Follow Rittal and site installation guidelines for mechanical mounting and clearances to ensure safe, reliable operation.
