Fixed COMBI Cable-Mounted Sockets with Connection Strip, Elektromet 921840 — red 400V and blue 230V

Fixed COMBI cable-mounted sockets Elektromet 921840 combine a red 400V three-phase outlet and a blue 230V single-phase outlet in a single fixed unit with an integrated connection strip for wiring. The unit is intended for permanent cable-mounted installation where simultaneous availability of 400V and 230V power is required. The design supports reliable supply to machines, portable tools and auxiliary equipment in workshops, industrial sites and temporary distribution points.

Advantages

The combined format reduces the need for separate distribution boxes by providing both 400V and 230V sockets in one compact assembly. An integrated connection strip facilitates secure and organized wiring during installation, improving serviceability and reducing installation time. The fixed, cable-mounted configuration is suitable for permanent installations, offering stable mechanical support and consistent electrical contact for continued operation in demanding environments.

Suitable for

• Workshops and machine shops requiring both three-phase and single-phase outlets
• Industrial production lines and equipment feeding points
• Temporary power distribution on construction sites or event installations
• Service and maintenance areas supplying tools and test equipment

Key specifications

• Voltage types: three-phase 400V (red) and single-phase 230V (blue)
• Fixed cable-mounted configuration with mounting provisions for permanent installation
• Integrated connection strip for wiring and terminal organization
• Durable housing suitable for workshop and industrial environments
• Designed for supplying machinery, portable equipment and auxiliary devices

How to use

Install the unit as a fixed, cable-mounted outlet at the chosen supply point following applicable electrical codes and safety rules. Secure the assembly mechanically and connect supply conductors to the integrated connection strip according to wiring diagrams and polarity/phase marking. After completing wiring and verifying tightness of terminals, mount protective covers or enclosures as required and test each socket with appropriate test equipment before connecting loads. Ensure that cable cross-sections and protective devices correspond to the connected loads and local regulations.

Usage recommendations

Use appropriate protective devices (circuit breakers, RCDs) rated for the connected loads and ensure periodic inspection of terminals and housing for signs of wear, corrosion or loose connections. Match plug types and current ratings to the socket outlets and avoid overloading either the 400V or 230V circuits.
