The 5UB2212-3KK is the clawless KK variant of the DELTA miro double socket in titanium white — a warmer white shade than the standard 5UB2212-3 white. It replaces the metal claw mechanism with direct screw fixing into the wall box, eliminating the risk of claw pressure damaging aged or brittle installation boxes. Two 10/16A 250V Schuko outlets with plug-in terminals and increased touch protection in a 70×70mm flush-mount format.

What does switching from 5UB2212-3 to -3KK actually change?

Two things: the color and the mounting method. The -3KK replaces the standard white of the -3 with titanium white — a slightly warmer shade closer to RAL 9010. More importantly, it replaces claw mounting with direct screw fixing. The metal swing claws are removed; the socket body screws directly into the threaded lugs of the wall box. This is the defining KK characteristic across the entire DELTA miro double socket range.

When does the KK clawless variant make more sense?

KK variants are purpose-built for renovation and retrofit work. Three scenarios favor clawless mounting: (1) the existing wall box is recessed deeper than 3mm — claws cannot bridge the gap, but screw fixing with longer screws can; (2) the box material is aged or brittle — claw pressure can crack older Bakelite or thin-metal boxes; (3) the box opening is slightly irregular — screw fixing is more forgiving than the symmetrical grip required by two opposing claws. For new construction with clean, standard boxes, the standard claw-mounted variant is faster to install.

Is the plug-in connection different from screw terminals?

Yes. Plug-in (push-in) terminals accept stripped conductor ends with a simple push — no screwdriver needed. They are faster for initial installation but slightly less flexible for rewiring compared to screw terminals. The 5UB2212-3KK uses plug-in terminals, matching the standard -3 variant. If you need screw terminals in a DELTA miro double socket, consider the 5UB2212-4 (aluminium metallic, screw terminals).

Frequently Asked Questions

Is titanium white noticeably different from standard white?

Under typical indoor lighting, the difference is subtle. Titanium white (approximately RAL 9010) has a marginally warmer, creamier undertone compared to the neutral, slightly cooler standard white. Side by side in direct light, titanium white appears softer; installed separately in different rooms, most users would not distinguish them.

Can I install this socket myself?

Yes, if you are comfortable with basic electrical work. The plug-in terminals accept 1.5–2.5mm² conductors with a simple push. Screw fixing requires aligning the socket with the box lugs and driving two screws — no special tools beyond a standard electrician's screwdriver. Always isolate the circuit at the distribution board before working on any socket outlet.
