The Siemens 5UB1555 is a white German Schuko-style (Type F) socket outlet from the DELTA i-system range, featuring an integrated labeling field. Rated at 10/16 A / 250 V AC, it fits a standard 55 × 55 mm frame for flush-mount indoor installation with screwless plug-in terminals. This is the budget title-block variant in the 5UB155x range — it gives you the labeling field for circuit identification but omits increased touch protection and the LED operating display.

What does the 5UB1555 leave out — and why might that be the right call?

Compared to the 5UB1552, the 5UB1555 drops the increased touch protection (the internal shutter mechanism). Compared to the 5UB1553, it also drops the LED. What remains is the labeling field — the one feature directly relevant to maintenance documentation and circuit traceability. In installations where touch protection is not mandated by code — such as sockets mounted above worktop height, in locked equipment rooms, or in facilities accessed only by trained personnel — the 5UB1555 is the most cost-effective way to get written circuit designation on each socket. You are not paying for safety features your installation does not require.

White vs electric white — which finish for which interior?

The 5UB1555 uses standard white, which is a brighter, cooler shade than the electric white (RAL 1013) used on most other 5UB155x models. Standard white pairs well with pure-white wall finishes, modern minimalist interiors, and environments lit with cool-white LED lighting. If your wall finish is a warm cream or off-white, the electric white models (5UB1552, 5UB1553) will blend more naturally. The difference is subtle but visible when the socket is mounted on a strongly cool- or warm-toned wall.
