Bus bar Rittal SV 9640.267, copper, 851 mm, single-piece

Rittal SV 9640.267 is a single-piece copper bus bar 851 mm long, designed to provide a reliable conductive main connection in switchgear and electrical enclosures. Manufactured from solid copper with a rectangular cross-section of 45 x 45 mm and a bar cross-section of 974 mm², this bus bar is intended for use in industrial power distribution systems that require robust current-carrying capacity and low electrical resistance.

Advantages

This single-piece copper bus bar offers uniform conductivity across its length and reduced contact resistance compared with multi-segment assemblies. Its solid construction and substantial cross-section support high current loads and heat dissipation, while the 851 mm length and standardized rectangular profile simplify integration into compatible busbar systems and enclosures. Being made of copper ensures predictable electrical characteristics and good corrosion resistance when installed in appropriate environments.

Suitable for

• Power distribution busbar systems in industrial switchgear
• Main conductive connection in electrical enclosures and distribution cabinets
• Applications requiring a single-piece conductor with high current capacity
• Retrofit or new installations where a 45 x 45 mm rectangular copper bar is specified

When it may not be suitable

This solid copper bus bar is not intended for use in low-current or signal-level applications where small conductors are appropriate. It may be unsuitable for installations with space constraints that cannot accommodate a 45 x 45 mm profile or for systems that require insulated or segmented busbar solutions. Additionally, this bare copper bar requires compatible mounting hardware and electrical clearances; it is not a finished insulated busbar assembly.

Key specifications

• Material: Copper (solid)
• Length: 851 mm
• Profile: Rectangular 45 x 45 mm
• Bar cross-section: 974 mm²
• Form: Single-piece conductor

How to use

Fit the bus bar into the designated support or mounting system inside the switchgear or enclosure, ensuring correct alignment with insulating supports and adequate clearance to adjacent conductive parts. Secure the bar at recommended fixing points using compatible clamps or brackets and make electrical connections with appropriately sized bolts and washers rated for the expected current. After installation, verify tightness of all connections and perform standard insulation and continuity tests before energising the system.

What to consider before purchase

• Confirm that the 851 mm length and 45 x 45 mm profile match the enclosure or busbar system dimensions
• Ensure the 974 mm² cross-section meets the current-carrying requirements of your application
• Verify compatibility with mounting supports, clamps and connector hardware
• Check required electrical clearances and any need for insulation or protective covers

Usage recommendations

Install and commission this copper bus bar following applicable electrical standards and manufacturer guidance for busbar systems. Use torque-specified fasteners, perform thermal and electrical tests under load, and consider protective measures such as covers or insulation in environments where accidental contact or condensation is possible.
