The Siemens 5UB1534 is a NEMA 5-20R socket outlet from the DELTA i-system wiring accessories range, bringing the North American receptacle standard into a European flush-mount form factor. Rated at 20 A / 125 V AC with a 2-pole-plus-earth configuration, it is designed for dry indoor locations. The 70 × 70 mm front plate integrates with standard DELTA i-system frames.

Where is a NEMA socket in a European wiring range actually used?

International hotels, corporate offices with North American tenants, embassy buildings, and specialized equipment rooms are the typical applications. These environments regularly host devices with NEMA 5-20P plugs — servers, AV equipment, laboratory instruments, and consumer electronics from the North American market. Rather than relying on travel adapters that can work loose or lack proper earthing, the 5UB1534 provides a native, permanently installed NEMA receptacle that is earthed and rated for continuous 20 A load.

How does this differ from the 5UB1535?

Both are NEMA sockets in the DELTA i-system range, but they serve different voltage classes and use cases. The 5UB1534 is a 125 V NEMA 5-20R without a cover — the right choice for standard North American 125 V equipment in a clean indoor setting. The 5UB1535 is a 250 V NEMA socket with a spring-loaded hinged cover, intended for higher-voltage equipment and installations where the cover adds mechanical protection for the receptacle when not in use.
