The Schneider Electric A9D56825 is an Acti9 iC60 RCBO — a combined residual current breaker with overcurrent protection, integrating earth-leakage and thermal-magnetic trip in a single 18 mm module. Rated 25 A at 50 °C with a 30 mA earth-leakage sensitivity, it protects a single pole (1P + Ns) on TN earthing systems.
Mounts on a DIN rail via the plug-on mechanism, occupying 2 pitches of 9 mm (18 mm total width). The top screw-clamp terminal accepts up to 25 mm² rigid or 16 mm² flexible; the bottom terminal accepts up to 16 mm² rigid or 10 mm² flexible. Tightening torque is 3.5 N·m top and 2 N·m bottom. Wire stripping length is 14 mm for the top connection and 13 mm for the bottom.
Rated breaking capacity is 10 kA Icn at 240 V AC, 50/60 Hz, conforming to IEC 61009-2-2. The device also complies with IEC 61009-1 and BS EN 61009-1. Electrical durability is 5000 cycles; mechanical durability is 20,000 cycles. IP20 rated (IP40 in modular enclosure). Overvoltage category II. Tropicalisation class 2. Local signalling includes ON/OFF and fault indication via the toggle.
