Bus bar Rittal SV 9640.237, copper, length 651 mm, single-piece

Rittal SV 9640.237 is a single-piece copper bus bar with a length of 651 mm and a substantial cross-section designed for reliable electrical distribution in switchgear and control cabinets. Manufactured from electrolytic copper, the bar delivers stable conductivity and mechanical strength for heavy-current and grounding applications. The product is intended for integration into industrial panels where a continuous, solid conductive path is required.

Advantages

The copper construction ensures low electrical resistance and dependable current carrying capacity, while the single-piece design eliminates joints that could introduce additional resistance or points of failure. Its 45×45 mm profile and 974 mm² cross-section provide robust mechanical support and thermal performance under load. The uniform shape and surface facilitate secure mounting and connection to clamps, busbar supports, and protective devices.

Suitable for

• Power distribution bus in switchgear and distribution panels
• Main grounding or equipotential bonding conductor
• Connections to circuit breakers, fuses and outgoing feeders
• Industrial control and automation cabinets requiring high-current conductors

When it may not be suitable

This solid copper bar is not intended for applications requiring flexible or braided conductors; it is a rigid component and requires appropriate mounting and clearances. It may not be suitable where space constraints demand smaller profiles or where non-conductive or insulated bus systems are required.

Key specifications

• Material: copper (electrolytic)
• Length: 651 mm
• Profile dimensions: 45 × 45 mm
• Cross-sectional area: 974 mm²
• Form: single-piece (solid)
• Typical use: power distribution and grounding in switchgear

How to use

Install the bus bar into the switchgear or cabinet using suitable insulated supports or busbar holders that match the 45×45 mm profile and ensure secure, vibration-resistant fixation. Ensure correct alignment and maintain required clearances to adjacent conductive parts according to applicable electrical standards. Make electrical connections with appropriately rated bolts, clamps or lugs; tighten to specified torque values and apply anti-corrosion treatment if recommended for the installation environment. Verify continuity and insulation before energizing the system.

What to consider before purchase

• Ensure the 651 mm length and 45×45 mm profile fit the intended mounting and enclosure layout
• Confirm the 974 mm² cross-section meets the current carrying and thermal requirements of your installation
• Check compatibility with existing clamps, supports and protection devices
• Verify required clearances and electrical standards for grounding and busbar installations

Usage recommendations

For reliable performance, use purpose-built busbar supports and follow manufacturer torque and mounting guidelines. Regularly inspect connections for signs of overheating, corrosion or loosening, and ensure that protective devices and temperature monitoring are in place for high-current applications.
