The 5UB5500-5KK is a black surface-mounted Type E French-standard socket from the Siemens DELTA range. A single-gang outlet with center protective contact — the male earth pin that defines the French CEE 7/5 standard. Unlike the IP44 DELTA fläche series, this is an IP20 indoor model without a hinged cover, designed for clean indoor surface-mount installations where the black finish is the aesthetic requirement.

What makes this a French-standard socket?

The center protective contact is the defining feature. Type E sockets have a protruding male earth pin on the socket face. Type E plugs have a matching female earth hole. This is the standard across France, Belgium, Poland, Czech Republic, Slovakia, and Francophone North Africa. The socket also accepts Type F Schuko plugs — the Schuko plug's side earth contacts still engage the socket's earth clips — making the 5UB5500-5KK usable in mixed-plug environments. The reverse is not true: a Type F (Schuko-only) socket cannot accept a Type E plug because the plug's male earth pin has no matching receptacle.

How does it differ from the DELTA fläche Type E socket (5UB4741)?

The 5UB4741 is the IP44 outdoor/damp-environment Type E socket with a hinged splash-proof cover, two-tone gray finish, and screwless plug-in terminals. The 5UB5500-5KK is the IP20 indoor version — no hinged cover, clean black finish, screw terminals. If the socket is going indoors and black matches the decor, the 5UB5500-5KK is the right fit. If it is exposed to splashing water or outdoor weather, the IP44 5UB4741 is the correct choice.

Installation

Surface-mounted directly on the wall — no flush box required. Screw terminals accept solid or stranded conductors. VDE 0620 certification covers use under severe conditions (mechanical stress, thermal load), so the socket is rated for demanding indoor environments like workshops and commercial kitchens. Halogen-free thermoplastic housing.
