The Schneider Electric A9N19532 is an Acti9 DPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — a single-module (36 mm wide) device combining a 10 A thermal-magnetic MCB with a 30 mA earth-leakage trip in one 1P+N package. The C-curve (magnetic trip 5–10 x In) handles moderate inrush from lighting or small motor loads without nuisance trips, while the integrated 30 mA residual-current element provides personal protection against earth faults.
Rated current In = 10 A, so it protects a final subcircuit drawing up to 10 A continuous — typical for lighting banks, socket outlets, or small appliances. Breaking capacity Icn = 4500 A at 220–240 V AC, 50/60 Hz, per EN/IEC 61009-2-1. If your site's available fault current exceeds 4.5 kA, you need a higher-rated upstream breaker or a current-limiting device to coordinate. Earth-leakage sensitivity is fixed at 30 mA — the standard threshold for personal protection against indirect contact. The device trips on both overcurrent (thermal-magnetic) and residual current, so it replaces two separate units (MCB + RCCB) in one DIN-rail slot. IP20 on the device body, IP40 inside the modular enclosure — suitable for dry indoor panels, not washdown environments.
Tropicalisation level 2 per IEC 60068-1 indicates the device withstands damp heat conditions typical of non-air-conditioned electrical rooms. The manufacturer provides CE declaration of conformity and, for EU markets, the UKCA marking. RoHS and REACH compliance documentation is available from Schneider Electric's product support pages — the paperwork is clean for cross-border shipments.
