The Siemens 5UB1835 is a green SCHUKO socket outlet from the DELTA style series, equipped with increased touch protection for enhanced contact safety. Rated at 16A/250V with an IP20 flush-mount design, it addresses installations where the safety feature must be built into the hardware rather than communicated through a printed label alone.

What does increased touch protection actually do?

The socket contacts are recessed deeper into the housing than on a standard SCHUKO outlet. This mechanical design choice means that when a plug is partially inserted, the live pins are not yet accessible to a finger reaching behind the plug. The additional recess depth — approximately 3mm beyond the standard VDE 0620 requirement — provides a meaningful safety margin in environments where untrained people interact with sockets, such as schools, kindergartens, hospital waiting areas, and public buildings.

How does 5UB1835 differ from 5UB1826?

Both are green DELTA style sockets, but they serve different safety strategies. The 5UB1826 uses the SV inscription to communicate safety supply status — it tells you what kind of circuit this is. The 5UB1835 has no inscription, but its recessed contacts physically protect you regardless of what circuit it is on. Choose 5UB1835 when the safety requirement is about preventing contact with live parts, not about labeling the circuit type. In many installations, the green color alone is sufficient to mark a safety circuit without the SV text.
