The A9D14810 is a Schneider Electric Acti9 iC60H RCBO — a combined residual-current circuit breaker with overcurrent protection in a single 18 mm wide, 1P+N module. It carries a 10 A rated current at 50 °C, a 30 mA earth-leakage sensitivity, and a 10 kA breaking capacity (Icn at 240 V AC, per IEC 61009-1).
Clip-on mounting to a 45 mm grid DIN rail. The module takes two 9 mm pitches of rail space. Neutral is on the left. IP20 on the body, IP40 inside a modular enclosure — that's standard for a panelboard, not a washdown location.
