The 5UH1066 is the increased-touch-protection cover plate in the DELTA style 68×68mm format, in titan white. It is the touch-protection counterpart to the standard 5UH1065 — same color, same series, different aperture geometry designed for the recessed contact face of erhöhter Berührungsschutz sockets.

5UH1066 vs 5UH1065 — what is the difference?

Both are DELTA style 68×68mm titan white cover plates. The 5UH1065 fits standard Schuko sockets. The 5UH1066 fits increased-touch-protection sockets. The difference is purely in the aperture geometry — the 5UH1066 accommodates the raised contact collar around the live and neutral openings of a touch-protection socket.

Does the 5UH1066 work with a standard Schuko socket?

No. Using the 5UH1066 on a standard socket would leave a visible gap around the socket face — the aperture is sized for the recessed collar of a touch-protection socket. Conversely, a standard cover such as the 5UH1065 will not physically fit over a touch-protection socket. Always match the cover plate type to the socket type.

Is there a DELTA profil equivalent?

Yes — the 5UH1056 is the DELTA profil 65×65mm equivalent: titan white, for increased-touch-protection Schuko sockets. The two serve the same function in different design series. Choose based on your frame system: DELTA profil 65×65mm frames use the 5UH1056; DELTA style 68×68mm frames use the 5UH1066.
