The 5SU9106-1DV06: The 10 mA IΔn is a sensitive earth-leakage threshold — it trips on leakage currents as low as 5–10 mA, which is the level specified for personal protection in wet or medical locations (IEC 60364-7-710 for medical rooms, for example). The C-curve (6 A) means the magnetic trip operates at 5–10× In (30–60 A), suited for loads with moderate inrush like small motors, lighting banks, or control transformers. The 1+N-pole form factor switches the line conductor and disconnects the neutral; the neutral is switched but not protected against overcurrent.
This class of combined RCD/MCB (RCBO) is installed in DIN-rail distribution boards for final circuits requiring both earth-leakage and overcurrent protection in a single module — common in residential, commercial, and light industrial panels. The 10 mA sensitivity makes it a typical choice for circuits supplying socket outlets in bathrooms, kitchens, or outdoor areas where additional shock protection is mandated. The 70 mm depth (D=70mm) is the standard Siemens RCBO footprint, fitting the same DIN-rail enclosures as the 5SU9 series.
