The Schneider Electric A9N19897 is a 2-pole Acti9 DCP Vigi residual current breaker with overcurrent protection (RCBO) rated at 32 A with a B tripping curve and integrated 30 mA earth-leakage protection — one unit covers both overcurrent and ground-fault on a single DIN-rail module. Breaking capacity is 10 kA Icn / Icu at 220...240 V AC 50 Hz per EN/IEC 61009-2-1 and EN/IEC 60947-2, so it clears a fault up to 10 kA without welding the contacts or cascading upstream.
Clip-on mount on standard DIN rail; 36 mm width (4 × 9 mm pitches) fits a 2-module slot in a consumer unit or distribution board. Tunnel terminals accept 1–35 mm² rigid or 1–25 mm² flexible; strip length 12 mm, tighten to 2 N·m top or bottom.
Designed and tested to EN/IEC 61009-2-1 and EN/IEC 60947-2, overvoltage category III, IP20 (IP40 in modular enclosure), tropicalisation class 2.
