Quick Summary
The DK PSM busbar provides modular 3-phase power distribution for 2000 mm rack enclosures. Repairing or expanding a live rack often forces costly downtime; this system supports retrofitting modules without powering down. The design aligns with CE safety standards, is suitable for IP-rated enclosures, and can integrate with SIL-aware safety architectures. Its modular aluminium construction and snap-fit socket modules reduce wiring and commissioning time, delivering lower total cost of ownership for industrial plants. Compatible with a 3 m connection cable and CEE connectors, it offers a scalable, maintenance-friendly path to reliable power distribution in data centers and manufacturing lines.
Product Information
Extended Description
7856323 Rittal: DK PSM busbar, 6-way, 3~, 32 A, Infeed: 1, For H: 2000 mm
Article number
DK 7856.323
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.

FAQs
Begin by aligning the 6-way DK PSM busbar along the vertical support rail inside the TS 8 enclosure. Use the 3 m CEE/EN 60309 connection cable to make the infeed connections, ensuring the infeed is set to 1. Snap-in modules can be added or moved while the system remains powered, provided proper lockout–tagout procedures are followed. Verify phase alignment and confirm the 32 A rating is not exceeded during commissioning.
The DK PSM busbar is a 6-way, 3~ system rated up to 32 A per infeed. It features a 3 m connection cable and uses a CEE connector for electrical hookup. It supports up to six module slots and is designed for infeed: 1, with the potential for redundant infeed configurations depending on connection direction. Operating range and compatibility with TS 8/TS IT/VX IT enclosures are standard.
Yes. The DK PSM busbar is explicitly designed for modular retrofitting, allowing socket modules to be snap-fitted into the support rail while the rack remains operational. This minimizes downtime and enables phased upgrades. Always follow manufacturer safety guidelines and use appropriate PPE during installation and module changes.
The system emphasizes safety with a shock hazard-protected rail design and CEE/EN 60309 connectors. It is intended for CE-compliant environments and is compatible with standard enclosure standards. Ensure installation occurs within the specified operating temperature range (5 °C to 45 °C) and humidity (5 to 95% non-condensing).
The modular DK PSM busbar reduces wiring complexity and speeds up commissioning, lowering labor costs during deployment. Live-retrofitting capability minimizes downtime, improving equipment availability. Over the long term, modular infeed upgrades simplify maintenance and spare-part planning, delivering a lower total cost of ownership in manufacturing and data-center environments.
