Why choose the fully-equipped variant?

The 5UB1922 is the only DELTA i-system Schuko socket that packs all three premium features into one unit. The spring-loaded hinged cover keeps dust out and adds a child-safe physical barrier. Increased touch protection recesses the live contacts beyond VDE 0620 test-finger reach. The transparent labeling field accepts a paper slip with circuit number or room name, visible at a glance without opening the cover. In a single product you get dust ingress protection (cover), electrical safety (recessed contacts), and installation documentation (label) — three concerns that would otherwise require separate products or handwritten tape on the wall plate.

How does the labeling field work in practice?

The labeling window sits below the socket opening on the cover plate. A small transparent flap opens to accept a paper label — typically 12–15 mm wide — printed or handwritten with the circuit designation. In distribution boards, office workstations, and hospital bed-head panels, this turns a row of identical-looking sockets into a labeled, auditable installation. For a 12-gang conference room setup, labeling each socket with its circuit breaker number reduces troubleshooting time from minutes of trial-and-error to a single glance.

How does the 5UB1922 compare to the two-feature 5UB1920?

The 5UB1920 shares the hinged cover and increased touch protection but omits the labeling field. The weight difference — 93 g vs. 101 g — reflects the additional transparent window and holder mechanism. If your installation requires circuit identification per socket (e.g. office workstations, hospital panels), the 5UB1922 is the correct choice. If dust ingress and tamper resistance are the only concerns, the 5UB1920 delivers the same protection at a slightly lower unit cost.
