Quick Summary
Rittal 7856008 DK PSM busbar distributes 3-phase power to modular racks in industrial enclosures. This solution is engineered for reliable, scalable power distribution in demanding manufacturing environments. In live operations, retrofitting active components without interrupting production is a common challenge; this busbar enables snap-fit module changes and two infeed options that support continuity during configuration updates. Certification details such as SIL, CE, or IP ratings are not listed in the provided data, so please verify with Rittal for exact certifications relevant to your region. The system also delivers space efficiency and safety through its shock-hazard-protected design and natural anodised aluminium rail. For engineering teams focused on modularity and enclosure readiness, the DK PSM busbar provides measurable business value alongside robust compatibility potential.
Product Information
Extended Description
7856008 Rittal: DK PSM busbar, 8-way, 3~, 16 A, Infeed: 2, For H: 2200 mm
Article number
DK 7856.008
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.
