Rittal Micro-switch for NH fuse-switch disconnectors Abschaltblock Pack of 5, MPN 3071.000

Replacement micro-switch (Abschaltblock) by Rittal intended for NH fuse-switch disconnectors and NH switch strips. Supplied as a pack of five, this accessory provides the contact switching and interlock functions required in many industrial and commercial electrical panels. The component is designed to be fitted into compatible NH disconnectors to enable safe operation, signalisation, and circuit breaking logic where mechanical separation and auxiliary switching are needed.

Advantages

The Rittal micro-switch pack offers consistent switching behaviour across units and simplifies maintenance by providing five identical spare parts in one delivery. Its design matches common NH disconnectors, enabling straightforward replacement without modifications. Using original-equivalent parts helps preserve the functional integrity of switchgear assemblies and reduces diagnostic time during repairs.

Suitable for

• Maintenance and repair of NH fuse-switch disconnectors in industrial switchboards
• Replacement of worn or defective auxiliary switches in NH switch strips
• Stocking as spare parts for electrical panel service teams

When it may not be suitable

This micro-switch is intended specifically for compatibility with NH fuse-switch disconnectors and NH switch strips; it may not fit or function correctly in equipment designed for other fuse systems or proprietary disconnectors. Applications that require custom contact arrangements, non-standard mounting, or environmental protections beyond typical panel conditions should verify compatibility before purchase.

Key specifications

• Function: auxiliary/micro-switch for NH disconnectors and NH switch strips
• Packaging: pack of five identical units
• Typical use: contact switching and mechanical interlock support within switchgear

How to use

Turn off and isolate the electrical supply before attempting replacement. Access the NH disconnector or switch strip according to the manufacturer's instructions and remove the faulty micro-switch. Fit the replacement unit in the same orientation, ensure correct mechanical engagement with the disconnector mechanism, and reconnect any auxiliary wiring following the panel wiring diagrams. After installation, restore power and perform functional checks to confirm correct switching and interlock behaviour.

What to consider before purchase

• Confirm compatibility with the specific model and size of NH disconnector or switch strip in your panel
• Verify contact configuration and mechanical mounting match the unit being replaced
• Ensure spare parts comply with any site-specific safety or inspection requirements

Usage recommendations

Store the pack in a dry, dust-free environment and use anti-static precautions if required. When replacing multiple units, label wiring and test each repair separately to maintain safe operation of the switchgear.
