The Siemens 5UB1563 is a DELTA i-system German Schuko socket outlet in orange, 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. The orange color follows the German electrical convention of marking ZSV (zusätzliche Sicherheitsversorgung) circuits — backup and UPS power supplies — for instant visual identification.

Why would I install orange sockets instead of white ones?

In German and European commercial electrical installations, orange sockets are the standard color code for circuits backed by a UPS or standby generator. When an electrician or facility manager sees an orange socket, they immediately know the connected equipment will stay powered during a mains failure. This is critical in offices for server racks, IT closets, security systems, and emergency lighting — any equipment that must not lose power unexpectedly. The built-in labeling field lets you add the specific circuit ID or UPS zone on top of the color code.

What is the difference between the orange 5UB1563 and the green 5UB1562?

Both are color-coded DELTA i-system sockets with identical electrical specifications. The difference is the circuit type they identify: orange (ZSV) marks backup-supplied circuits, while green (SV) marks safety-relevant circuits such as those feeding emergency lighting or fire alarm systems. Choose the color that matches your installation's circuit designation standard.

Frequently Asked Questions

Does the orange color fade over time?

The color is molded into the thermoplastic material, not painted on, so it remains stable under normal indoor conditions. As an IP20-rated socket it is designed for indoor use only, away from direct UV exposure that could accelerate fading.

Can I use this socket on a normal mains circuit?

Technically yes — it functions identically to any other DELTA i-system Schuko socket. However, using orange sockets on non-backed-up circuits defeats the purpose of color coding and can cause confusion during maintenance or emergency situations. It is best practice to reserve orange sockets for UPS/backup circuits.
