Bus bar Rittal DK 7856.010 — aluminium, 1 piece

Rittal DK 7856.010 is an aluminium bus bar supplied as a single piece intended for electrical distribution and busbar systems in enclosures. It is designed to provide a conductive connection for power distribution in control cabinets and switchgear assemblies where an aluminium bus bar is required for reliable current carrying and system integration. The product supports modular integration into existing rack and enclosure systems and can be combined with plug-in modules and measurement options when used with compatible monitoring systems.

Advantages

The aluminium construction offers a balance of conductivity and lower weight compared with some other materials, facilitating easier handling and installation in confined cabinet spaces. Supplied as one piece, the bus bar simplifies inventory and reduces the need for on-site splicing. It supports modular system configurations including one or two infeeds and selectable phase arrangements, and it can provide redundancy after changing the plug-in module's direction of connection. In conjunction with compatible measurement equipment it enables monitoring functions.

Suitable for

• Power distribution in control cabinets and electrical enclosures
• Switchgear assemblies requiring a lightweight aluminium bus bar
• Modular systems with plug-in modules and configurable phase arrangements
• Installations where the option for measurement integration is needed

When it may not be suitable

This aluminium bus bar may not be suitable for applications that require higher conductivity materials such as copper for very high current density or where specific material approvals mandate non-aluminium conductors. It is also not appropriate where detailed mechanical dimensions, mounting accessories or insulation covers are required but not supplied with the single-piece item; those components must be verified and obtained separately.

Key specifications

• Material: aluminium
• Quantity: 1 piece
• Configuration: supports one or two infeeds and up to three phases depending on system setup
• Compatibility: intended for use in enclosure and control cabinet busbar systems
• Functional features: supports redundancy via plug-in module orientation and a measurement option when used with compatible monitoring systems

How to use

Install the bus bar according to the enclosure manufacturer's layout and mounting instructions, ensuring correct alignment with plug-in modules and phase connections. Verify mechanical fit and electrical clearances inside the cabinet before securing. When configuring infeeds and phases, follow the system wiring plan and change plug-in module orientation as required to achieve desired redundancy. For measurement capability, integrate the bus bar with the compatible monitoring system according to the monitoring equipment instructions.

What to consider before purchase

• Confirm that an aluminium conductor is acceptable for the intended current ratings and regulatory requirements
• Verify mechanical dimensions, mounting method and whether additional accessories (insulation covers, connectors, mounting hardware) are required
• Ensure compatibility with existing plug-in modules, phase arrangements and any monitoring system planned for measurement

Usage recommendations

Follow all applicable electrical installation standards and local regulations. Use appropriate torque settings on terminal connections, ensure proper insulation and clearance distances, and perform electrical testing after installation. For measurement functions, integrate with the specified monitoring system and verify sensor connections and configurations.
