The Siemens 5UB1511-0KA is the kit-packaged version of the DELTA i-system titanium-white SCHUKO socket. Where the standard 5UB1511 is the socket insert alone, the -0KA variant bundles the insert with a matching single-gang titanium-white frame — a complete out-of-the-box package for one i-system socket position.

Insert-only vs kit — what does the -0KA suffix mean?

In Siemens DELTA i-system packaging logic, the base part number 5UB1511 delivers the socket mechanism and its 55 × 55 mm cover plate — enough to populate an existing frame. The -0KA suffix adds the surrounding decorative frame in the same titanium-white finish, making it a ready-to-install kit. For new installations or when the frame type is not already decided, the kit removes the need to order the frame as a separate line item. For multi-gang installations that share a single multi-frame, the insert-only 5UB1511 avoids redundant frame purchases.

What is in the box?

The 5UB1511-0KA kit contains: (1) the SCHUKO socket insert with screwless plug-in terminals, 55 × 55 mm titanium-white cover plate, and metal mounting claws with screw-fixing points; (2) a single-gang DELTA i-system decorative frame in matching titanium white. The socket is rated 16A/250V, IP20, for indoor flush-mount installation in a standard 45 mm wall box. Halogen-free thermoplastic throughout.

Compatibility note

This is a DELTA i-system product with 55 × 55 mm inserts. It is not compatible with DELTA profil (65 × 65 mm) frames or DELTA style (68 × 68 mm) frames. If you have an existing Siemens DELTA installation, verify which design line the frames belong to before ordering — the insert dimensions are the definitive identifier.

Frequently Asked Questions

Does the kit include the wall box?

No. The wall box (Unterputzdose) is a separate item sourced from the electrical installation supplier. The kit covers everything visible on the wall surface: socket insert, cover plate, and decorative frame.

Can I use this frame with a different-color socket insert?

Yes. The DELTA i-system frame is mechanically separate from the socket insert. You can mix frame and insert colors within the i-system ecosystem — for example, a titanium-white frame with an electric-white insert — though this is uncommon in practice.
