The Siemens 5UB1912 is the white DELTA i-system Schuko socket that pairs a hinged cover with an integrated labeling field and increased touch protection. It is the 5UB191x-line counterpart to the electric-white 5UB1902 — identical in every respect except the white shade, which is closer to RAL 9010 (pure white) rather than the warmer RAL 1013 of the 5UB1902.

What does the hinged cover protect against?

The spring-loaded flap (opening angle 150°) covers the socket face when no plug is inserted, providing mechanical protection against dust ingress, light water spray from cleaning, and accidental finger contact. The unit remains rated IP20 — the hinged cover does not make it weatherproof. For wet or outdoor locations, a dedicated IP44 socket with a sealed enclosure is required.

How does the integrated labeling field work?

The labeling field is moulded into the socket face and covered by a transparent film. Unlike clip-on label holders that can be lost or dislodged, the integrated design keeps the circuit identification intact through years of cleaning, maintenance, and plug insertions. This is particularly valuable in commercial and public buildings where multiple identical-looking sockets must remain individually identifiable.

How does this differ from the electric-white 5UB1902?

The 5UB1912 and 5UB1902 are functionally and mechanically identical — same hinged cover, same labeling field, same screwless terminals, same increased touch protection. The sole difference is the white shade: 5UB1912 is a pure white (similar to RAL 9010), while 5UB1902 is electric white (similar to RAL 1013, a warm off-white). Choose the 5UB1912 to match a titanium white DELTA i-system frame and switch programme, or when pure white is the specified finish.
