The Siemens 5UB1855-0KK combines two safety-oriented design choices in one device: increased touch protection (deeper-set contacts) and clawless mounting (screw-only fastening, no metal claws). Rated at 16A/250V for indoor flush-mount use with a titan white 68×68mm cover plate.

Why combine clawless mounting with increased touch protection?

The clawless design omits the spring-loaded metal claws that normally grip the inside of the flush-mount box. This makes the socket easier to install in narrow or shallow boxes where claws risk interfering with adjacent wiring, and in hollow-wall boxes with thin walls that claws could deform. Pairing clawless mounting with increased touch protection addresses installations that are both physically constrained and safety-sensitive — for example, a kindergarten classroom with shallow retrofit boxes, or a laboratory with hollow-wall construction where enhanced contact safety is mandatory. The socket is secured by screws alone; proper screw torque is essential for long-term mechanical stability.
