The Siemens 5UB4722 is a surface-mounted DELTA fläche double Schuko socket with horizontal outlet layout — two sockets positioned side by side in a single IP44 enclosure. The horizontal format is the natural choice when wall space is constrained vertically (under a window, above a workbench) or when two devices sit next to each other. Both outlets have independent hinged spring-flap covers with increased touch protection.

Horizontal vs vertical double socket: how to choose

The DELTA fläche double sockets come in two orientations: horizontal (5UB4722, 75 × 134 × 54 mm) and vertical (5UB4724, 151 × 66 × 54 mm). The choice is purely about the available wall space and the cable routing direction. Horizontal suits installations where devices sit side by side; vertical works better in narrow wall strips or where cables drop from above. Electrically and functionally, the two are identical — same 16A/250V rating, same screwless terminals, same IP44 protection.

Wiring a DELTA fläche double socket

Both outlets share a common supply via pre-wired internal connections — one cable entry feeds both sockets. Screwless spring-clamp terminals accept up to 2.5 mm² solid or stranded conductors. The double terminals at each contact support clean loop-through to downstream sockets. Surface mounting with claw-and-screw fastening — no flush wall box required.
