The Schneider Electric A9DC8616 is an Acti9 iCV40H residual current circuit breaker with overcurrent protection (RCBO), combining a 16 A thermal-magnetic MCB and a 300 mA earth-leakage module in a single 36 mm wide, 1P+N package that clips onto a DIN rail. Rated Icn of 10,000 A at 230 V AC, 50/60 Hz per EN/IEC 61009-2-1, so it clears a bolted fault up to that level without blowing apart — important for panel coordination downstream of a higher-rated upstream breaker.
Listed as current production (active lifecycle stage). This is a standard catalogue item in the Acti9 range, not a phase-out or last-time-buy part.
