The Siemens 5UB1914 is a unique combination in the DELTA i-system range: an orange ZSV-marked Schuko socket that brings together a hinged cover, an integrated labeling field, and increased touch protection. No equivalent exists in the 5UB190x line — this is the only orange socket in DELTA i-system to include all three features in a single 55×55 mm unit.

Why would I need an orange socket with a hinged cover AND a labeling field?

Orange ZSV sockets identify circuits backed by a UPS or standby generator. In hospitals, data centres, and emergency call centres, these sockets must remain operational during a mains failure. Adding a hinged cover protects against dust and cleaning moisture in clinical and technical environments, while the integrated labeling field lets each socket carry a unique circuit identifier — which UPS branch feeds it, which equipment it is reserved for, or which phase it belongs to.

What does the orange ZSV marking mean?

Orange sockets marked ZSV (Zentrale Sicherheitsversorgung / central safety power supply) are reserved for circuits backed by an uninterruptible power supply (UPS) or a standby generator per DIN VDE 0100-710. The orange colour provides an instant visual signal that distinguishes backed-up outlets from general-purpose mains sockets during both normal operation and emergency scenarios.

How does this differ from the orange basic socket 5UB1911?

The 5UB1911 is a basic orange Schuko socket — no cover, no labeling field, no increased touch protection. The 5UB1914 adds all three: a spring-loaded hinged cover, an integrated writable labeling field, and increased touch protection. For clinical or technical environments where orange ZSV sockets must be individually identifiable, physically protected when idle, and finger-proof, the 5UB1914 is the correct choice.
