The 5UB1943 is the entry-level model in the 5UB194x carbon metallic range — DELTA i-system Schuko sockets that include increased touch protection and a labeling field as standard features. Finished in dark anthracite-grey (~RAL 7016), it provides the core safety and labeling functions in a single 55×55mm insert.

What gap does the 5UB1943 fill in the carbon metallic range?

In the 5UB192x carbon metallic series, touch protection and labeling field exist on separate models — 5UB1924 has touch protection but no labeling field; 5UB1923 has a labeling field but no touch protection. The 5UB1943 is the first carbon metallic Schuko socket to combine both in one insert without adding a hinged cover or other features. If you want a carbon metallic socket that is safe (passive contact shrouding per VDE 0620) and identifiable (labeling window for circuit numbers), and you do not need an LED or surge protection, the 5UB1943 is the direct pick.

Carbon metallic or aluminum metallic — does it matter?

Electrically and mechanically, the 5UB1943 (carbon metallic, 85g) is identical to the 5UB1940 (aluminum metallic, 84g). The 1g weight difference is paint formulation and coating thickness. The choice is purely aesthetic: carbon metallic is a dark anthracite-grey (~RAL 7016) that pairs with carbon metallic DELTA i-system frames and darker wall finishes; aluminum metallic is a silver tone (~RAL 9006) that reads as a lighter, more contemporary accent. Both use the same thermoplastic base material, screwless terminals, 55×55mm insert format, and 10/16A 250V rating.

How does the 5UB194x carbon range tier out?

• 5UB1943 (85g): Touch protection + labeling — the essentials, no extras.
• 5UB1944 (87g): Adds an operating display LED for at-a-glance power status.
• 5UB1945 (105g): Upgrades to overvoltage protection with a dual-function display that reports both power and protection circuit health.

All three share the carbon metallic finish, increased touch protection, labeling field, screwless terminals, and 55×55mm insert format.
