Quick Summary
Rittal 7856010 PSM busbar delivers modular power distribution for industrial enclosures, enabling scalable, reliable rack power. When racks must be upgraded or retrofitted, downtime and wiring errors cost time and money; this solution supports fast, safe reconfiguration with minimal system interruption. While the data references ETIM EC002762 and ECLASS 27371306 codes, verify any specific certifications such as CE marking or IP ratings with the supplier to ensure site compliance. Designed for TS 8, TS IT, or VX IT enclosures, it supports a 4-way layout with two infeeds and 3-phase redundancy, matching a 16 A rating. The combination of shock-hazard protection and plug-in modularity helps optimize lifecycle costs and maintenance planning.
Product Information
Extended Description
7856010 Rittal: DK PSM busbar, 4-way, 3~, 16 A, Infeed: 2, For H: 1200 mm
Article number
DK 7856.010
Design
With 2 infeeds (jack), 3-phase redundancy
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.
Material
Aluminium section, natural anodised

Product description
DK PSM busbar, 4-way, 3~, 16 A, Infeed: 2, For H: 1200 mm
Feature: 4-way, 3~, 16 A infeed with two infeeds. Business Impact: Delivers scalable 3-phase power distribution with built-in redundancy, reducing single-point failures and enabling safe, quick topology changes. Application: Rack power distribution in tall industrial enclosures where uptime matters. Feature: Modular design allows retrofitting while the system is operational. Business Impact: Minimizes downtime and enables in-service upgrades without full shutdowns, cutting maintenance windows and improving asset availability. Application: Live rack reconfiguration in manufacturing lines and control panels. Feature: WAGO X-COM connection system. Business Impact: Ensures reliable, snap-fit electrical contacts with fast field assembly, lowering installation time and fault rates. Application: Industrial control panels requiring robust plug-in connections. Feature: Aluminium, natural anodised construction. Business Impact: Provides corrosion resistance and lightweight handling, reducing maintenance costs and improving lifecycle durability. Application: Environments with exposure to dust and humidity. Feature: Operating range and environmental tolerance. Business Impact: Supports consistent performance across typical workshop and plant conditions (5 °C to 45 °C, 5–95% humidity). Application: Enclosures in factory floors and automated cells. Feature: Compatibility with TS 8, TS IT, VX IT enclosures and 1200 mm height. Business Impact: Simplifies system integration and standardizes installation in common Rittal rack families, reducing design time. Application: New installations and upgrades in standardized IT/industrial enclosures. Feature: Measurements option with CMC III system. Business Impact: Enables power monitoring and phase measurement for improved energy management and fault diagnosis. Application: Data- and energy-sensitive automation environments. Note: The data set includes ETIM and ECLASS classification codes that support procurement workflows and ERP tagging, enhancing supplier searchability and interoperability.

FAQs
The DK 7856.010 is designed for TS 8, TS IT, and VX IT enclosure families, offering a 4-way, 3~ power distribution with two infeeds. Its modular approach and WAGO X-COM connections simplify integration with existing rail-based systems and reduce installation time, even in retrofit scenarios.
This model provides 3~ per infeed across two infeeds, delivering 16 A maximum per channel. The modular slots support up to four modules, enabling scalable distribution for active components while maintaining phase integrity and redundancy to minimize downtime during maintenance or expansion.
Yes. The design explicitly supports retrofitting while operational, with a shock-hazard-protected support rail and snap-in socket modules. This enables upgrades or modifications to occur with minimal impact on ongoing processes and reduces costly shutdowns.
Installers should verify enclosure compatibility, enforce proper rail mounting, and confirm connector integrity with the WAGO X-COM system. Observe standard electrical safety practices, verify temperature/humidity limits (5 °C to 45 °C, 5–95% RH), and consult local CE or IP-related requirements for site-specific compliance.
Benefits include reduced downtime during upgrades due to rapid retrofit capability, fewer wiring errors thanks to plug-in connections, and improved lifecycle cost through modularity and shock-hazard protection. Energy monitoring via the CMC III option supports better energy management and early fault detection for overall maintenance savings.
