Industrial switch/disconnector module Rittal SV 9666.410, white, for 1x NH fuse

Rittal SV 9666.410 is a white switch/disconnector module designed to accept a single NH fuse (1x NH). It is supplied as an individual module intended for integration into industrial or commercial electrical distribution and control panels where a compact NH fuse holder combined with a load-disconnection function is required. The module provides a straightforward method to mount and switch NH fuses within standard panel assemblies while keeping a small footprint.

Advantages

The module offers a compact form factor and is finished in white to blend with typical enclosure interiors. It combines a dedicated NH fuse holder with a switching/disconnection mechanism to simplify installations that require both overcurrent protection and manual isolation. Supplied as a single unit, it is suitable for retrofits or new panel builds and minimizes the need for separate components.

Suitable for

• Industrial control and distribution panels that use NH fuses
• Commercial electrical installations requiring a dedicated 1x NH fuse holder with disconnect capability
• Retrofit projects where a compact, single-module solution is preferred

When it may not be suitable

This module accepts only one NH fuse size and is not intended for applications requiring multi-fuse assemblies or integrated protection for several circuits. It does not replace full multi-pole isolators or motor starters where additional control functions, auxiliary contacts, or overload protection are required.

Key specifications

• Colour: white
• Function: switch/disconnector module with NH fuse holder for 1x NH
• Mounting: panel-mounted module for integration into electrical enclosures
• Application area: designed for industrial and commercial electrical distribution and control panels
• Supply: single module (delivered as one unit)

How to use

Install the module into a suitable panel cut-out or mounting rail according to the panel manufacturer and applicable electrical standards. Fit the correct NH fuse of the appropriate rating for the circuit and secure it in the holder. Use the integrated switching/disconnection mechanism to isolate the circuit for maintenance or emergency disconnection. Ensure wiring and earthing are completed by a qualified electrician and that the installation complies with local regulations.

What to consider before purchase

• Verify that the module accepts the NH fuse size and rating required for your circuit
• Confirm panel space and mounting compatibility with your enclosure or distribution board
• Ensure that a single-fuse module meets your protection and isolation needs, or if multi-pole or additional protective devices are required

Usage recommendations

Use this module together with correctly rated NH fuses and follow applicable standards for panel wiring and earthing. Have installation and fuse selection performed or checked by a qualified electrician to ensure safe and code-compliant operation.
