The Schneider Electric A9D56806 is an Acti9 iC60 RCBO — a combined residual current breaker with overcurrent protection in a 1P+N, 18 mm wide modular package. It protects a single pole against overload and short-circuit (B curve, 3–5 x In magnetic trip) and adds integrated earth-leakage protection at 30 mA sensitivity, all in one DIN-rail module. Rated 6 A at 50 °C with a breaking capacity of 10 kA Icn at 240 V AC (IEC 61009-2-2), it's sized for final subcircuits in TN earthing systems — think lighting, socket outlets, or small appliance feeds where you need both overcurrent and earth-leakage protection in a single slot. The thermal-magnetic trip unit handles the overcurrent side; the integrated residual current module covers the 30 mA leakage. IP20 on the terminals, IP40 inside the modular enclosure — fine for dry indoor distribution boards.
Neutral on the left, phase on the right — standard Acti9 layout. Wire stripping length is 14 mm top, 13 mm bottom. Tightening torque: 3.5 N·m on the top screw clamp, 2 N·m on the bottom. The toggle gives local ON/OFF and fault indication — useful for quick visual checks on the panel door.
Rated for 5,000 electrical cycles and 20,000 mechanical cycles.
