The Schneider Electric A9N19874 is an Acti9 DCP Vigi residual current breaker with overcurrent protection (RCBO) — a single module that combines a 16 A thermal-magnetic MCB with integrated 30 mA earth-leakage protection in a 3-pole package. Rated breaking capacity is 10 kA Icu at 220...240 V AC per EN/IEC 60947-2, with an Icn of 6000 A per EN/IEC 61009-1 — enough for most distribution sub-panels in commercial and light industrial installations.
Tunnel terminals accept 1...35 mm² rigid or 1...25 mm² flexible on top or bottom; strip length 12 mm, tighten to 2 N·m. Local signalling shows ON, OFF, and fault trip via the toggle position.
