The Siemens 5UB1854 is the labeling-field variant in the DELTA style SCHUKO socket range, combining a transparent label window, a status indicator light, and increased touch protection in a single flush-mount unit. Rated at 16A/250V for indoor use with a 68×68mm cover plate.

What does the integrated labeling field do?

The cover plate includes a transparent window that accepts a paper label or printed insert. Installers use it to mark the circuit number, purpose, or location directly on the socket face — eliminating separate label holders or handwritten tape. In commercial and industrial distribution boards, typical labels include circuit designations like "UPS Circuit 3," "Server Rack A Row 2," or "Dedicated Line — Do Not Switch." The label is protected behind the transparent cover and remains legible for the life of the installation.

How does increased touch protection work?

The socket contacts are recessed deeper than on a standard SCHUKO outlet, making accidental finger contact with energized parts significantly less likely during plug insertion and removal. This exceeds the baseline VDE 0620 requirement and is specified for installations in schools, laboratories, public-access areas, and any location where untrained personnel may interact with sockets.

How does the 5UB1854 compare to the 5UB1852 and 5UB1853?

The three DELTA style socket variants form a clear feature hierarchy. The 5UB1853 is the base model — no cover, no label, standard touch protection. The 5UB1852 adds a spring-loaded hinged cover for dust and contact safety. The 5UB1854 adds the labeling field, status indicator, and increased touch protection — making it the most information-rich variant. All three share the same 68×68mm footprint and plug-in terminals, so they are mechanically interchangeable in the same flush-mount box. Choose the 5UB1854 when circuit identification and enhanced contact safety are both required.
