The Siemens 5UB1511 is the standard titanium-white Type F SCHUKO socket in the DELTA i-system range. The i-system is Siemens' contemporary flush-mount design line with 55 × 55 mm cover plates — a distinct ecosystem from the DELTA profil line and its 65 × 65 mm format. Frames, covers, and inserts are not interchangeable between i-system and profil.

i-system vs profil — which design line fits your installation?

DELTA i-system (55 × 55 mm) and DELTA profil (65 × 65 mm) are two separate flush-mount ecosystems within the Siemens DELTA portfolio. The i-system is the contemporary line with compact square plates and a clean, minimal aesthetic suited to modern residential and commercial interiors. The profil line offers a wider range of feature variants — hinged covers, increased touch protection, overvoltage protection — across a larger plate format. The choice between them is typically locked in by the existing frames and boxes in the building; retrofitting from one to the other requires replacing all inserts and frames throughout the installation.

What does the 5UB1511 include?

The 5UB1511 is the socket insert only. It includes the SCHUKO socket mechanism, the 55 × 55 mm titanium-white cover plate, and the metal mounting claws with supplementary screw-fixing points. The surrounding decorative frame is ordered separately from the DELTA i-system frame range. The socket flush-mounts into a standard 45 mm wall box with claw-and-screw fixing for secure retention in both new plaster and retrofit drywall installations.

Frequently Asked Questions

Can I use this with my existing DELTA profil frames?

No. DELTA i-system uses 55 × 55 mm inserts; DELTA profil uses 65 × 65 mm. The two lines are mechanically incompatible. If you have profil frames installed, choose from the 5UB14xx socket range instead.

Is there a version without mounting claws?

Yes — the 5UB1511-0KK is the clawless variant for screw-only mounting in plastic or shallow drywall boxes where metal claws would interfere with the box walls.
