Bus bar Rittal SV 9640.232 copper, 651 mm length, single piece

Rittal SV 9640.232 is a single-piece copper bus bar, 651 mm in length and with a cross-sectional area of 1354 mm², designed for reliable conductive connections in electrical distribution and panel busbar systems. Manufactured from E-Cu (electrolytic copper) and sized at 45 x 45 mm, this bus bar is intended for installation inside industrial control cabinets, distribution panels and switchgear where a solid, high-conductivity conductor is required for power distribution and grounding tasks.

Advantages

The solid copper construction provides high electrical conductivity and low resistance, supporting efficient current flow and reduced voltage drop. Supplied as a single piece at a standard 651 mm length, the bus bar simplifies assembly and reduces the need for onsite joints or splices. Its 45 x 45 mm profile and substantial 1354 mm² cross-section offer robust mechanical strength and thermal capacity, suitable for demanding electrical loads.

Suitable for

• Internal power distribution in industrial control cabinets and distribution panels
• Main or sub-distribution busbars in switchgear and electrical enclosures
• Applications requiring a solid copper conductor for grounding or heavy current carrying
• Retrofit and new-build electrical installations where a 651 mm bus length matches cabinet layouts

When it may not be suitable

This single-piece bus bar may not be appropriate where custom lengths are required and no on-site cutting or modification is planned. Systems that rely on insulated or coated busbars for specific safety or corrosion-resistant requirements may need a different product if bare copper is not acceptable. For installations with space constraints that do not accommodate the 45 x 45 mm profile, a smaller cross-section or alternative busbar format should be considered.

Key specifications

• Material: Electrolytic copper (E-Cu)
• Length: 651 mm
• Cross-section (bar): 1354 mm²
• Profile dimensions: 45 x 45 mm
• Supply format: Single piece bus bar

How to use

Install the bus bar securely within the cabinet or enclosure using appropriate mechanical fasteners and insulating supports according to the electrical layout and local standards. Ensure correct alignment with termination points, and make connections using suitable bolted or crimped terminals rated for the conductor size and current. Verify that clearances, creepage distances and insulation requirements are met before energizing. If cutting or drilling is necessary, use tools and procedures suitable for copper to avoid deformation or contamination.

What to consider before purchase

• Confirm that the 651 mm length and 45 x 45 mm profile fit the intended enclosure and mounting arrangement
• Ensure the 1354 mm² cross-section and thermal rating meet the required current-carrying capacity for your circuit
• Verify whether bare copper is acceptable for your application or if insulated/coated busbars are required for safety or corrosion protection
• Plan for required accessories: insulating supports, terminal connections and correct torque-rated fasteners

Usage recommendations

Use the Rittal SV 9640.232 bus bar in installations where a single, solid copper conductor simplifies power distribution. Pair it with appropriate insulating supports and correctly sized termination hardware, and follow local electrical codes for spacing and grounding. Regular visual inspection for secure connections and signs of overheating will help maintain reliable operation.
