The Siemens 5UB4713 is the only light gray socket in the DELTA fläche range. Its integrated labeling field — a writable surface on the socket face — lets electricians mark circuit designations directly on the device, eliminating the need for separate label tags. IP44 surface-mounted construction with hinged spring-flap cover and screwless plug-in terminals.

Why a labeling field matters on an IP44 socket

In multi-socket outdoor or damp-room installations — distribution panels, workshop walls, plant rooms — quickly identifying which circuit breaker feeds which socket prevents downtime and wiring errors. The 5UB4713 solves this at the device level: write the circuit number or equipment name directly on the socket face, visible even when the hinged cover is closed. On sockets without a labeling field, adhesive tags and stickers peel off in damp conditions over time.

Light gray vs standard gray: is there a functional difference?

No. The light gray color (similar to RAL 7035) is purely aesthetic. Electrically and mechanically, the 5UB4713 is identical to the standard gray 5UB4718 which also has a labeling field. The choice between them is purely about which color integrates better with the surrounding wall or installation environment.
