## Long description

Rittal SV 9677.450 is a set of three busbar connection clamps engineered for use with NH fuse rails. These terminal blocks are intended to provide a reliable mechanical and electrical connection for NH fuse systems in panels, switchboards, and distribution enclosures where NH fuse rails of the corresponding size are installed. The clamps are supplied as a set of three and are compatible with NH fuse rail installations used in electrical distribution and maintenance operations.
Advantages
The Rittal busbar connection clamps deliver stable contact pressure and a compact footprint, helping to keep wiring layouts tidy inside switchgear and distribution cabinets. Their construction supports consistent electrical conductivity and reduces the risk of loose connections in NH fuse assemblies. Being a set of three ensures a coordinated solution for multi-pole or grouped fuse arrangements and simplifies replacement or retrofit work.
Suitable for
Connecting NH fuse rails in electrical distribution panels and switchboards
Maintenance and replacement of existing NH fuse installations
Retrofit projects where NH fuse rails need a secure busbar connection
Industrial and commercial electrical enclosures using NH fuse systems
When it may not be suitable
This set is specifically designed for NH fuse rail connections; it may not fit non-NH fuse rail profiles or rail sizes outside the compatible range. The clamps do not replace circuit protection devices themselves and are not intended as a standalone current-carrying busbar without the appropriate NH fuse rail and associated protective equipment.
Key specifications
Quantity: set of three connection clamps
Function: busbar-to-NH-fuse-rail mechanical and electrical connection
Application: intended for use with NH fuse rails in panels and switchboards
Form factor: compact terminal clamp designed for panel mounting
How to use
Install the clamps onto the NH fuse rail following the rail manufacturer’s mounting guidelines and ensure correct orientation for the fuse holders. Secure the clamps with the appropriate fasteners and torque settings recommended for NH fuse installations to achieve reliable contact pressure. Verify electrical continuity and proper mechanical fixation after installation, and carry out tests according to local electrical codes before returning the circuit to service.
What to consider before purchase
Confirm compatibility with the specific NH fuse rail profile and size used in your equipment
Ensure the set of three clamps matches the number of poles or grouped fuse positions required
Check mounting space inside the panel or switchboard to accommodate the clamp footprint
Review installation torque and fastener type needed for a reliable electrical connection
Usage recommendations
Use the Rittal SV 9677.450 clamps as part of a complete NH fuse rail assembly, follow the NH rail and panel manufacturer's installation instructions, and perform proper torqueing and electrical tests to maintain safe and reliable operation.
