The Schneider Electric A9N19676 is an Acti9 DPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — one module wide, 1P+N, rated 20 A at 30 °C with a B-curve magnetic trip (3–5 × In). The integrated earth-leakage protection is Type AC, 300 mA sensitivity, instantaneous trip. The thermal-magnetic trip unit handles overloads and short-circuits; the residual-current block adds the ground-fault layer.
Neutral is on the left, phase on the right. The toggle gives local ON/OFF indication. For a panel builder, the 1P+N format saves space compared to a separate MCB + RCCB pair, and the 20 000 electrical / 20 000 mechanical cycles match the durability of a standard final-circuit breaker.
