Extended Description
7856090 Rittal: DK PSM Plus socket module, CEE 7/3 (type F), 4-way, black, non-switchable, with thermal overcurrent protection
Article number
DK 7856.090
Design
non-switchable
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. The various modules, earthing pins, IEC320 etc. may be inserted into the support rail in any combination. This is easily achieved, even by non-electricians, thanks to the shock hazard protected plug & play system.

FAQs
The socket module is designed to snap into a vertical support rail, using a single infeed and snap-fit into the rack system. Ensure the rail has a free module slot, then align the module with the rail, push firmly to engage the snap mechanism, and connect the 110–230 VAC supply. The 4 sockets and earth pins are then ready for quick, safe connections to connected devices.
This module operates on 110–230 V AC at 50/60 Hz, with a maximum rated current of 16 A per socket. It is a 4-way, non-switchable socket module featuring CEE 7/3 (type F) receptacles and earth pins (Type F, CEE 7/4). The module length is 250 mm, and the packs contain 1 unit with a weight of 0.355 kg.
Yes, the DK 7856.090 uses a WAGO WINSTA MIDI style electrical connection, which ensures fast, reliable plug-in connectivity and reduces wiring time during installation. This compatibility supports standardized, repeatable assemblies in modular rack configurations, improving consistency across multiple cabinets and simplifying maintenance.
The module is ideal for modular power distribution in electrical cabinets and industrial automation racks. It supports single-phase infeed configurations with four active sockets, enabling quick provisioning of power to active components, earthing, and safety features in control panels, data centers, and machine enclosures.
The module offers thermal overcurrent protection per socket and is designed for 5–45 °C ambient temperatures with 5–95% non-condensing humidity. Its plug-and-play system minimizes shock hazards during installation, and the anodised aluminium housing plus PA6 GF 30 V1 socket inserts provide durability in harsh industrial environments.
