The 5UB2211-3KK is a white DELTA line Schuko double socket outlet from Siemens, rated for 10/16A at 250V. It provides two integrated Schuko outlets in a 70×70mm flush-mount format with snap-in clawless mounting — the socket clips directly into a standard 60mm wall box without metal gripping claws. Increased touch protection is standard.

What does the KK suffix mean?

KK stands for "Keine Krallen" — German for "without claws." In Siemens DELTA wiring accessories, the KK suffix designates the clawless variant. Instead of metal swing claws that grip the inside of the wall box when mounting screws are tightened, the KK version is fixed with screws directly into the box. This eliminates the risk of claw pressure cracking older or brittle installation boxes and provides a more secure fit when the wall box is slightly recessed.

White vs titanium white — what is the color difference?

The 5UB2211-3KK is finished in white, a neutral, slightly cooler white compared to the titanium white of the 5UB2211-3. Both are glossy thermoplastic. The choice is aesthetic — white blends with pure-white wall finishes, while titanium white has a warmer undertone that suits cream or off-white surroundings.

Does snap-in mounting require a special wall box?

No. The 5UB2211-3KK fits standard 60mm-diameter flush-mounted wall boxes. Snap-in (Rastbefestigung) mounting uses spring-loaded plastic tabs that engage the box edge — no tools beyond pushing the socket into place. Because there are no metal claws, the socket sits flush even if the box is slightly recessed, a common issue with claw-mounted designs in older installations.

Frequently Asked Questions

Is this a complete unit or do I need a separate frame?

The 5UB2211-3KK is a complete DELTA line double socket — the 70×70mm faceplate and two outlets are a single integrated unit. Unlike DELTA i-system (55×55mm modular inserts), no separate frame or cover plate is needed.

Can I install this outdoors or in a bathroom?

No. The IP20 rating restricts this socket to dry indoor locations. For wet areas, Siemens offers IP44 and IP55 variants with hinged covers in the DELTA line and DELTA miro ranges.
