The Siemens 5UB4705 is a surface-mounted DELTA fläche Schuko single socket for outdoor and damp-environment installations. Its defining feature is the simultaneous-locking hinged cover — the spring flap latches at multiple points around the perimeter, creating a consistent IP44 seal against splashing water from any direction. Increased touch protection (child-safe shutters) is built into the socket contacts.

What does simultaneous locking mean on a socket cover?

Unlike a standard spring flap that hinges from the top and relies on a single bottom catch, the simultaneous-locking mechanism engages multiple latch points around the cover perimeter when closed. This distributes sealing pressure evenly, maintaining the IP44 rating even after thousands of open/close cycles. The design is specific to Siemens DELTA fläche outdoor sockets — standard indoor hinged covers do not offer this multi-point sealing.

How does the 5UB4705 compare to other DELTA fläche single sockets?

The DELTA fläche single-socket range builds up in a feature ladder. The entry-level 5UB4711 has a standard hinged cover without touch protection. The 5UB4717 adds increased touch protection but keeps a basic hinged cover. The 5UB4705 is the only model that combines touch protection with the simultaneous-locking cover — making it the right choice when both child safety and reliable environmental sealing matter. If key-operated security is also needed, see the lockable 5UB4716.

Installation and wiring

Surface-mounted directly onto the wall — no flush box required. The base plate accepts cable entry from multiple directions via break-out knockouts. Screwless plug-in terminals accommodate solid and stranded conductors up to 2.5 mm², with double terminals at each contact for clean loop-through to downstream sockets. Overall dimensions: 75 × 66 × 54 mm.
