## Summary description

Rittal DK 7856.321 is an aluminium bus bar supplied as a single piece for electrical power distribution in enclosures and switchgear. Designed for reliable conductive connection, it suits industrial control cabinets and distribution systems requiring a durable aluminium conductor. Supplied quantity: 1 piece.

## Long description

The Rittal DK 7856.321 aluminium bus bar is a single-piece conductive rail designed for distributing power within electrical enclosures. It supports one or two infeeds and can be used with one to three phases depending on installation. The unit is designed to remain electrically continuous if the plug-in module's direction of connection is changed, providing redundancy in typical cabinet power bus applications.
Advantages
Made of aluminium for good conductivity and lightweight handling, this bus bar is supplied as a single piece for straightforward installation. It is compatible with measurement options when used together with a CMC III system, enabling integration into monitoring and diagnostic setups. The design supports flexible phase configurations and redundant operation after reorientation of plug-in modules.
Suitable for
Power distribution inside electrical control cabinets
Bus systems requiring one to three-phase connections
Installations where integration with CMC III measurement systems is needed
Environments that benefit from redundancy when plug-in modules are reconnected
When it may not be suitable
This aluminium bus bar is intended for internal cabinet use and may not be suitable for outdoor or corrosive environments without additional protection. It does not include separate plug-in modules, cables, or measuring devices; those must be specified and installed separately according to system requirements.
