The Siemens 5UB1367-1 is the silver-metallic version of the DELTA style CEE 7 universal socket — identical to the white 5UB1367 in every technical respect except the cover plate finish. The -1 suffix in Siemens DELTA nomenclature consistently denotes the silver/platinum metallic colorway.

Silver sockets — aesthetic choice or functional code?

In German VDE installation practice, silver/grey sockets are conventionally assigned to EDV (IT/data processing) circuits — the color signals to users that this outlet is on a dedicated IT circuit with separate earthing and possibly UPS backup. Not every project follows this convention, and in many contemporary interiors silver is chosen purely for its aesthetic compatibility with stainless steel, glass, and monochrome architectural palettes. Either way, the 5UB1367-1 provides the same CEE 7 universal receptacle behind a metallic-finish plate that the white version cannot match.

White or silver — how to choose?

The white 5UB1367 fits traditional and warm-toned interiors. The silver 5UB1367-1 suits cool-toned modern spaces, IT/communications rooms, and anywhere the switchgear is expected to read as a metal finish rather than a plastic one. Both sockets carry the same 10/16A, 250V rating with increased touch protection and plug-in terminals — the decision is purely about the wall it is going into.
