The Siemens 5UB1853-0KK is the clawless variant of the DELTA style SCHUKO socket in titan white. It differs from the standard 5UB1853 in one key detail: it lacks the metal mounting claws, relying solely on screw fastening for installation. Rated at 16A/250V for indoor flush-mount use.

What does clawless mounting mean in practice?

Standard DELTA style sockets use spring-loaded metal claws that grip the inside of the flush-mount box, supplemented by screws. The clawless (-0KK) variant omits the claws entirely and is secured by screws alone. This results in a slightly lighter unit (0.074 kg vs. 0.083 kg for the standard version) and can simplify installation in boxes where claw clearance is tight or where the box material (e.g., certain hollow-wall boxes) does not provide a reliable claw grip. The trade-off: clawless sockets depend entirely on screw torque for mechanical stability.

When should you specify clawless over standard?

Choose the -0KK variant for: (1) installations in narrow or shallow flush-mount boxes where claws risk interfering with adjacent wiring, (2) hollow-wall boxes with thin or flexible walls that claws could deform, (3) retrofit projects where the existing box lacks the lip profile that claws normally engage. For standard solid-wall flush-mount boxes, the standard 5UB1853 with claws provides faster, more forgiving installation.
