The Schneider Electric A9DC4706 is an Acti9 iCV40H RCBO — a combined overcurrent and earth-leakage protective device — rated 6 A with 30 mA sensitivity, C-curve, and a 10 kA breaking capacity at 400 V AC per EN/IEC 61009-2-1. It protects three poles plus neutral in a single modular unit, so it fits a 3P+N outgoing circuit where you need both short-circuit and ground-fault protection in one DIN-rail package.
The 30 mA earth-leakage sensitivity provides additional protection against indirect contact and fire risk from ground faults, integrated into the same thermal-magnetic trip unit. That means one device replaces a separate MCB and RCD in the same DIN-rail width — 10 module pitches (90 mm wide) for the 3P+N configuration.
Clip-on mounting to a standard DIN rail. Neutral is on the left; connection pitch is 18 mm between phases and 9 mm between phase and neutral. Tunnel-type terminals accept 1–16 mm² rigid or 1–10 mm² flexible cable; strip length is 14 mm, tighten to 2 N·m. IP20 rated (IP40 in modular enclosure).
