Power extension Rittal DK 7240.110 — 3x Type D outlets, 2 m cable, 230 V 16 A, indoor (grey)

Rittal DK 7240.110 is a compact indoor power extension that provides three Type D grounded AC outlets with a fixed 2 m mains cable. Rated for 230 V and up to 16 A, this grey socket strip is intended for reliable and straightforward distribution of mains power to equipment in control cabinets, workshops, offices and other indoor installations where a small number of permanently available grounded outlets is required.

Advantages

The unit combines a short fixed cable and three Type D outlets in a compact aluminium duct-compatible housing, offering a space-saving solution for installation inside enclosures or on machine frames. Its 16 A rating supports typical small to medium electrical loads and the grey finish integrates unobtrusively into industrial and office environments. The fixed-cable design reduces loose connections and installation time compared with multiple individual connectors.

Suitable for

When it may not be suitable

This power extension is designed for indoor fixed installations and is not intended for outdoor use or exposed environments without additional protection. It lacks an integrated switch or surge protection, so it may not be suitable where switched control, overcurrent protection beyond the rated 16 A, or surge suppression is required.

Key specifications

How to use

Mount the unit where additional grounded outlets are needed, ideally within an enclosure or on a mounting rail compatible with aluminium ducts. Connect the fixed 2 m cable to a properly rated 230 V, 16 A supply circuit, ensuring the supply is switched off during installation. Plug equipment into the Type D outlets and verify load requirements do not exceed the 16 A rating. For safety, ensure that earthing and protection devices in the installation comply with local regulations.

What to consider before purchase

Recommendations

Use the Rittal DK 7240.110 for fixed, indoor power distribution to equipment with moderate power draw, install it inside enclosures or on appropriate mounting rails, and avoid connecting high inrush or aggregated loads that exceed 16 A. Regularly inspect the cable and sockets for wear and ensure the overall installation follows local electrical safety standards.
