The Siemens 5UB1561 is a DELTA i-system German Schuko socket outlet in electric white, featuring an integrated labeling field and status indicator. Rated at 16A/250V with screwless plug-in connection terminals, it is designed for flush mounting in standard 55x55mm insert format and is compatible with all frames of the DELTA line range.

What makes the DELTA i-system socket different from a full-plate DELTA line socket?

The 5UB156x series belongs to the DELTA i-system, where the socket insert (55x55mm) is paired with a separately selected cover frame and plate. This modular approach gives you flexibility to mix and match colors and materials across frames, switches, and sockets. In contrast, DELTA line full-plate sockets like the 5UB158x series come as a one-piece complete unit with an integrated 80x80mm plate — simpler to order but with less design flexibility.

What is the labeling field used for?

The integrated labeling window on the cover plate allows you to identify individual circuits directly on the socket — e.g., "Office 12A," "Meeting Room AV," or circuit numbers. This is especially useful in commercial and office environments where multiple identical-looking sockets serve different circuits and quick identification saves troubleshooting time. The status indicator provides at-a-glance confirmation that the socket is live.

Frequently Asked Questions

Does this socket include increased touch protection (erhöhter Berührungsschutz)?

No. The standard 5UB156x models do not have increased touch protection. If you need that safety feature, consider the DELTA line 5UB1582 (white) or 5UB1583 (electric white) which include it.

Is this socket compatible with non-Siemens frames?

The DELTA i-system insert is designed for Siemens DELTA line frames. While the 55x55mm format is an industry-standard size, compatibility with third-party frames is not guaranteed and should be verified with the frame manufacturer.
