Design
With rocker switch
Product description
The socket strips are available in various country-specific variants with different functional elements. Special attention has been devoted to practical, universal fastening: Variable attachment facilities have been created with an angle bracket which may be inserted in four positions. Hence, for example, the 482 mm long socket strips may optionally be mounted on 482.6mm (19") mounting angles, the 482.6 mm (19") mounting frame, on the enclosure frame, or in the rear section of the wall-mounted distributor. Socket strips with a length of more than 482 mm can only be fitted on the enclosure frame. The socket strip may be inserted into all sections with a 25 mm hole pattern, without the need for additional mounting accessories. This makes selection much easier, as well as providing additional flexibility and saving on warehousing. Provision has also been made for cable routing of the infeed, and when mounting in the 482.6 mm (19") section there is adequate space to route the infeed between the socket strip and the profile rail without kinks. The arrangement of the IEC 320 sockets at a 45° angle allows unrestricted use of angular connectors.

Product description
DK Socket strip, CEE 7/3 (type F), 7-way, 250 V, 16 A, LHD: 482,6x44x44 mm, With rocker switch
The DK 7240.220 socket strip houses 7 CEE 7/3 Type F sockets, rated for 250 V AC and up to 16 A, providing a reliable, centralized power source within control panels. This arrangement reduces wiring complexity and potential misconnections, boosting equipment uptime in manufacturing lines and machine frames. It also supports flexible installation with variable mounting positions, including 482.6 mm lengths that can be mounted on enclosure frames, 19" mounting angles, or rear sections of wall-mounted distributors, saving time during project setup. The included 2 m H05VV-F3G1.5 connection cable and wire-end ferrules simplify pre-wiring and termination, enabling faster commissioning and fewer field assembly errors. Its 45° socket orientation facilitates easy access to angular connectors, improving accessibility in tightly packed cabinets. Made from a natural anodised aluminium section with polycarbonate socket inserts, the strip delivers durability in harsh industrial environments while maintaining a clean, professional enclosure appearance. The design also accommodates a 25 mm pitch pattern for straightforward integration with other components, reducing spare parts and inventory. Practical guidance notes remind engineers to consider a charging current reserve to prevent activation spikes during startup, further improving system reliability and lifecycle costs.

FAQs
The DK 7240.220 supports flexible mounting with a 482.6 mm length and a 452.5 mm mounting footprint. It can be mounted on enclosure frames, 19 inch mounting angles, or in the rear section of wall-mounted distributors. For lengths exceeding 482 mm, installation is recommended on the enclosure frame. The product includes two mounting brackets and assembly parts to simplify alignment and secure attachment.
The socket strip features seven CEE 7/3 type F sockets, arranged for easy access. It is rated for 250 V AC at up to 16 A. The sockets are oriented at a 45° angle to accommodate angular connectors and reduce wiring congestion. A 2 m H05VV-F3G1.5 supply cable with ferrules is included to ensure secure terminations and reliable field wiring.
Yes. The design supports 482.6 mm (19”) mounting options via four-position angle brackets, mounting frame, or enclosure frame. When using socket strip lengths longer than 482 mm, installation is limited to the enclosure frame. It is compatible with 25 mm hole patterns, facilitating integration with standard 19” rails and related components.
Plan cable routing to leave space between the socket strip and profile rail to prevent kinks. Follow the note suggesting a charging current reserve to mitigate incorrect activation from startup spikes. The 45° socket arrangement enables easier access with angular connectors, reducing bending strain on cables and improving long-term reliability in automated environments.
Pre-wired assembly with a 2 m feed cable, included mounting brackets, and standardized 482.6 mm length reduce field wiring time and warehouse complexity. The aluminium profile with polycarbonate sockets provides robust durability, lowering replacement and maintenance costs. Flexible mounting options and 25 mm pitch compatibility minimize part variety, enabling faster installation and lower lifecycle costs in control panels and automation cabinets.
