Quick Summary
Rittal DK PSM busbar is a modular power distribution solution for rack cabinets. It enables safe, scalable in-rack power provisioning with a 7-way, 3-phase layout and two infeeds for flexible configuration. This design addresses downtime during upgrades by allowing retrofits without powering down the system, a critical advantage in live-panel environments. While the data here does not list explicit CE, IP, or SIL markings, these are common considerations for enclosure-based power systems and should be verified on the final unit. The modular concept supports quick socket-module snap-in installation and shock hazard-protected operation, aligning with professional expectations for industrial control cabinets and IT rack applications. In practice, the solution reduces lifecycle costs and improves upgrade velocity for data centers and manufacturing lines.
Product Information
Extended Description
7856006 Rittal: DK PSM busbar, 7-way, 3~, 16 A, Infeed: 2, For H: 2000 mm
Article number
DK 7856.006
Design
With 3 m connection cable (connector type CEE/EN 60 309)
Product description
The modular system facilitates basic configuration of the racks, thanks to a vertical support rail with single-/3-phase infeed. The various socket modules to supply the active components may be snap-fitted into the support rail. This can even be done whilst the system is operational, because the support section is shock hazard-protected.
Benefits
Modules may be retrofitted whilst operational.
Technical specifications
Each plug-in module picks off a phase on the support rail, either from infeed or from the redundant infeed, depending on the direction of connection.

Product description
DK PSM busbar, 7-way, 3~, 16 A, Infeed: 2, For H: 2000 mm
Feature → Business Impact → Application: The DK PSM busbar delivers a 7-way, three-phase distribution with 16 A rating, enabling scalable power routing to multiple modules and devices within a single enclosure. This translates to better space utilization, predictable current sharing, and simplified board-level upgrades, especially in compact rack environments used in automation and control gear. Feature → Business Impact → Application: Two infeed options and a 3 m CEE/EN 60309 connection cable provide redundancy and flexible deployment, reducing single-point failures and enabling safe maintenance windows. Application-wise, technicians can retrofit active components without system shutdown, boosting uptime in TS 8, TS IT, or VX IT enclosures up to 2000 mm high. Feature → Business Impact → Application: Aluminium natural anodised construction offers robust mechanical integrity with corrosion resistance, supporting long service life in harsh factory environments and easing retrofits in harsh ambient conditions. Feature → Business Impact → Application: The modular socket modules snap into the vertical rail, supporting rapid reconfiguration as production lines change, ensuring you stay compliant with evolving device mixes and minimizing downtime.

FAQs
The DK PSM busbar uses a vertical support rail system with snap-fit socket modules that can be added or removed while the system is energized, provided all safety procedures are followed. It supports enclosure types TS 8, TS IT, and VX IT, with a height specification up to 2000 mm. Compatibility is ensured by the 3 m CEE/EN 60309 cable and the dual infeed design, which provides reliable phase distribution for 7 slots in a single rail.
The busbar is designed for 3~ three-phase operation with a rated current of up to 16 A and seven module slots. Infeed is 2, allowing flexible phasing and redundancy. The 3 m connection cable and CEE interface support robust field connections, improving reliability in dynamic industrial environments and enabling scalable power provisioning across multiple components.
Yes. The system is designed for retrofitting while the system remains operational, thanks to modular socket modules that snap into the support rail. This capability minimizes downtime during upgrades or reconfiguration, a common challenge in control cabinets that service automated equipment or IT gear in manufacturing and data centers.
The data set does not list explicit CE, IP, or SIL marks for this unit. In practice, devices of this type typically align with CE safety standards and enclosure protection requirements; confirm exact certification marks on the delivered unit and with Rittal documentation. This ensures you meet site regulatory obligations and customer-required safety certifications before deployment.
Retrofitting with the DK PSM busbar reduces downtime by enabling module-level changes without shutting down the entire rack. The aluminum, naturally anodised construction supports long service life in industrial settings, while modular infeed design and snap-in socket modules simplify ongoing upgrades. This translates to lower maintenance costs, faster configuration changes, and improved total cost of ownership for power distribution in automation environments.
