Load switching busbar module Rittal SV 9677.015 for NH fuse, group 00, 160A

Rittal SV 9677.015 is a load switching busbar module engineered for NH fuses of group 00 with a rated current of 160 A. It is intended to provide a secure switching and connection point inside electrical distribution and control panels where NH-type fuse protection is required. The module integrates with switchgear assemblies to enable reliable load isolation and safe maintenance procedures.

Advantages

This load switching busbar module offers a compact design suitable for installation in confined switchgear spaces while maintaining robust electrical contact performance for 160 A circuits. It is built to match the form factor and mechanical interfaces of NH group 00 fuses, enabling straightforward replacement and consistent operation. The component supports safe load disconnection and contributes to orderly fault protection schemes in industrial and commercial panels.

Suitable for

• Switchgear and distribution panels using NH group 00 fuses
• Industrial control cabinets requiring load isolation at up to 160 A
• Commercial electrical installations with modular fuse systems
• Maintenance workflows where clear, accessible fuse switching is needed

When it may not be suitable

This module is not suitable for applications that require fuse types other than NH group 00 or where rated currents exceed 160 A. It should not be used as a substitute for devices that combine protective relays, circuit breakers, or other active protection functions beyond simple load switching and fuse accommodation.

Key specifications

• Intended fuse type: NH, group 00
• Rated current: 160 A
• Function: load switching busbar module for fuse-based isolation
• Mounting: designed for integration into switchgear/distribution panels
• Application environment: industrial and commercial electrical installations

How to use

Install the busbar module into the designated fuse holder position inside the panel following the switchgear manufacturer's mounting guidelines. Fit the appropriate NH group 00 fuse into the module and secure all terminals to the panel busbars ensuring correct phase orientation and torque on connections. Use the module to isolate loads by withdrawing the fuse or operating the integrated switching feature, and always follow lockout/tagout and safety procedures during maintenance.

What to consider before purchase

• Confirm compatibility with NH group 00 fuse dimensions and holder layout in your panel
• Verify that 160 A rated current meets the maximum load and protective coordination requirements
• Ensure mechanical fit and clearance within the intended switchgear or distribution cabinet
• Check that the module addresses required isolation and safety practices for your installation

Usage recommendations

For reliable operation, install the module in accordance with the panel manufacturer's instructions, use NH group 00 fuses rated for the intended circuit, and perform periodic inspections of terminals and contacts to maintain secure connections and proper thermal performance.
