The 5UB4732 is the increased-touch-protection triple socket in the DELTA fläche IP44 range — three Type F Schuko outlets in a single 201mm-wide surface-mounted housing, with recessed live contacts that meet the erhöhter Berührungsschutz standard. It is the top-tier triple in the DELTA fläche catalog: single-tone gray, plug-in terminals, and the passive safety geometry that no other triple in the range offers.

5UB4732 vs 5UB4731 — what does the extra cost buy you?

The two DELTA fläche triple sockets differ on three points. First, touch protection: the 5UB4732 has recessed contacts that prevent a straight finger from reaching live parts — a passive safety measure with no moving parts to fail. The 5UB4731 has standard-contact geometry. Second, finish: the 5UB4732 is single-tone gray; the 5UB4731 is two-tone dark gray/light gray. Third, terminals: plug-in on the 5UB4732, spring-flap on the 5UB4731 — both are screwless and tool-free, just different actuation mechanisms. If the installation spec or environment calls for increased touch protection, the 5UB4732 is the required choice — there is no third triple socket with this feature.

What does increased touch protection mean on a triple socket?

Each of the three socket apertures has a deeper contact recess and a smaller opening than a standard Schuko socket. A child's finger, a screwdriver tip, or any straight object of typical finger diameter cannot physically reach the live contacts. The protection is geometric — no shutter, no spring, no mechanism that can jam or wear out. The trade-off is that some older plugs with thicker bodies may feel slightly snug during insertion. For kitchens, workshops, and any installation in an occupied space where untrained hands might be near the socket, the passive safety is worth the marginal extra cost.

Installation and wiring

Surface-mounted via Ø 4.5mm screw holes. Plug-in terminals accept solid conductors — strip and push. All terminals are doubled for clean daisy-chain wiring to downstream sockets. Cable entry through sliding nipples (8–13.5mm Ø) maintains the IP44 seal. At 201mm wide and 357g, the unit needs a flat wall surface with enough clearance for the hinged cover to open fully.
