The Siemens 5UB1915 is the white DELTA i-system Schuko socket with hinged cover and increased touch protection. It is the touch-protected hinged-cover socket in the 5UB191x line — the counterpart to the electric-white 5UB1905, distinguished only by the pure white (RAL 9010) shade.

What is the difference between 5UB1915 and 5UB1917?

Both are white, flush-mount, hinged-cover Schuko sockets in the 55×55 mm DELTA i-system format with screwless terminals. The sole difference: the 5UB1915 includes increased touch protection (erhöhter Berührungsschutz) — internally shuttered live and neutral apertures — while the 5UB1917 does not. If the installation code or site policy requires increased touch protection, the 5UB1915 is the correct choice.

How does this differ from the electric-white 5UB1905?

The 5UB1915 and 5UB1905 are functionally and mechanically identical. The only difference is the white shade: 5UB1915 is pure white (similar to RAL 9010), while 5UB1905 is electric white (similar to RAL 1013, a warm off-white). Choose based on which white matches the existing DELTA i-system frames and switches in the installation.

Does the hinged cover make increased touch protection redundant?

No. The hinged cover protects the socket when it is not in use (plug removed, flap closed). The internal shutters protect when the socket is in use — during plug insertion, or if the cover is deliberately held open. A partially inserted plug can leave live pins exposed, and only the internal shutters guard against contact in that scenario. For publicly accessible areas such as schools, kindergartens, and hospital waiting rooms, both layers of protection are advisable.
