The Siemens 5UB4716 is the explicitly lockable single socket in the DELTA fläche surface-mounted range. It is the designated security model — specified by Siemens as the lockable variant for installations requiring controlled power access. The key-operated mechanism locks the hinged cover in the closed position, preventing unauthorized plug insertion. IP44-rated with increased touch protection and screwless plug-in terminals. Made in Spain.

What makes the 5UB4716 different from other lockable DELTA sockets?

While the 5UB4714 also has a lockable cover, the 5UB4716 is the formally designated lockable model in Siemens catalog logic. It carries a different internal classification and is stocked specifically for security-critical applications. The locking mechanism itself differs in keying and durability — Siemens positions the 5UB4716 for high-traffic areas where the lock is used daily: communal facilities, public buildings, and building services installations. The 5UB4714 is the lighter-duty alternative for general lockable-socket applications.

Installation requirements

Surface-mounted on any flat wall. The lock adds no extra depth — the housing dimensions match other DELTA fläche single sockets. Cable entry via push-on nipples for 8–13.5 mm round cables. Screwless terminals accept up to 2.5 mm² conductors with double terminals per contact for loop-through wiring.
