The Schneider Electric A9N19653 is a DPN Vigi RCBO (residual current circuit breaker with overcurrent protection) from the Acti9 range, combining a 10 A thermal-magnetic MCB with integrated 30 mA earth-leakage protection in a single 1P+N module. Type AC detection means it trips on sinusoidal AC residual currents only — the standard choice for general-purpose socket and lighting circuits where no pulsed or DC fault currents are expected.
Rated at 10 A (In) with a B-curve magnetic trip of 3 to 5 × In, so it clears short-circuit faults between 30 A and 50 A — well matched to final circuits with resistive or lightly inductive loads where nuisance tripping from inrush is a concern. The 30 mA residual sensitivity provides personal protection against indirect contact per IEC 60364.
Deployment context
Occupies 4 × 9 mm pitches (36 mm) for the 1P+N configuration — the neutral is on the left, and the outgoing terminal accepts up to 16 mm² rigid or 10 mm² flexible cable.
