The 5UH1056 is the increased-touch-protection cover plate in the DELTA profil range — a titan white 65×65mm thermoplastic frame specifically designed for Schuko socket inserts with erhöhter Berührungsschutz. The center aperture has a modified geometry to fit the recessed-contact socket face that standard cover plates cannot accommodate. Same titan white finish as the 5UH1047, but the fitment is different.

Why do I need a different cover plate for increased-touch-protection sockets?

A socket with increased touch protection has a deeper contact recess — the live terminals sit further back inside the socket body, and the plastic face around each aperture has a raised collar. A standard cover plate's aperture is sized for a flush or near-flush socket face; it will not seat properly over the raised collar of an increased-touch-protection socket. The 5UH1056 has an aperture designed for this geometry — the collar passes through cleanly and the plate sits flat against the mounting frame. Using a standard cover plate on an increased-touch-protection socket leaves a visible gap and compromises the IP20 seal.

How do I know if I need the 5UH1047 or the 5UH1056?

Look at the socket insert. If the socket face is flat or nearly flat with the mounting frame, use the 5UH1047 (standard). If the socket face has raised collars around each plug aperture — typically marked with the erhöhter Berührungsschutz symbol or notation — you need the 5UH1056. Both are titan white, both are 65×65mm DELTA profil. The difference is purely the aperture geometry. If in doubt, order the socket insert and cover plate together to ensure compatibility.
