The Siemens 5UB1350 is the titanium-white variant of the DELTA i-system CEE 7 universal socket — the warmer, more architecturally flexible sibling of the electric-white 5UB1348. It accepts both Type E (French) and Type F (Schuko) plugs through the combined center-pin and side-clip earthing system.

When does titanium white make sense?

Electric white (5UB1348) is deliberately high-contrast — it signals "this is the switchgear" against a colored wall. Titanium white does the opposite — it is closer to RAL 9010, a softer white that disappears into cream, beige, and off-white wall finishes. In hotels, residential, and high-end commercial interiors where the electrical installation is supposed to recede visually, titanium white is the default specification. The color difference is subtle head-on but becomes obvious when both are installed side by side under the same lighting.

What accounts for the weight difference?

At 0.087kg, the 5UB1350 is heavier than the 0.069kg 5UB1348. The additional mass comes from a more substantial contact carrier assembly — the internal dimensions are slightly larger, which may offer marginally better heat dissipation at sustained full load. For most installations the weight difference has no practical impact, but it reflects a different internal tooling set between the two color variants.
