The Siemens 5UB4715 is a surface-mounted DELTA fläche Schuko socket with increased touch protection — spring-loaded shutters behind each contact opening that only retract when both pins of a Schuko plug are inserted simultaneously. This is the standard child-safety feature required by modern electrical installation codes. IP44 hinged cover and thermoplastic housing for outdoor and damp-room use.

How increased touch protection works on a Schuko socket

Inside each contact opening, a spring-loaded plastic shutter blocks access to the live terminal. The shutter is mechanically designed so it only retracts when both pins (line and neutral) of a standard CEE 7/4 Schuko plug press against it simultaneously. A child inserting a single object into one hole cannot open the shutter — the mechanism requires equal pressure on both sides. This is purely mechanical and requires no power to function.

5UB4715 vs 5UB4714: with or without the lock?

The 5UB4715 and 5UB4714 are otherwise identical DELTA fläche sockets — same IP44 rating, same increased touch protection, same screwless terminals. The only difference: the 5UB4714 has a key-lockable cover, while the 5UB4715 has a standard non-locking spring flap. If you do not need to control who can plug into the socket, the 5UB4715 is the more economical choice.
