What this RCBO delivers
The Schneider Electric A9D47220 is a 2-pole Acti9 iC60 RCBO — a combined overcurrent and residual-current device rated for 20 A with 30 mA earth-leakage sensitivity. Curve B magnetic tripping (3...5 x In) suits circuits with low inrush, like lighting or general socket outlets. The 10 kA Icn breaking capacity at 220...240 V AC (15 kA Icu per EN/IEC 60947-2) covers most distribution boards in residential or light commercial builds. Thermal-magnetic trip unit, no electronics to fail on the overcurrent side. IP40 in a distribution enclosure, IP20 bare. Toggle control with local ON/OFF/fault trip indication.
Limitation class 3 per the latter standard. Carries quality marks NF, KEMA-KEUR, IMQ, VDE. Overvoltage category III per IEC 60364. Tropicalisation class 2 for humid environments — 95 % RH at 55 °C.
