The Schneider Electric A9D68610 is an Acti9 iDPN Vigi residual current circuit breaker with overcurrent protection (RCBO) — a combined 1P+N MCB and 30 mA or 300 mA earth-leakage block in a single 36 mm wide module. Rated 10 A with a B-curve (magnetic trip at 3–5 × In) and a 6 kA breaking capacity at 230 V AC, it clips onto a DIN rail in a distribution board as an outgoing circuit for lighting or socket-outlet protection where both overcurrent and earth-leakage protection are required in one device. The 73 mm depth fits standard 85 mm tall enclosures.
Earth-leakage sensitivity is 300 mA (fixed), which provides equipment protection (fire prevention) rather than personal shock protection; for personnel protection a 30 mA variant would be used. Integrated earth leakage means no separate RCCB module is needed, saving one DIN module width.
