The Schneider Electric A9DC8610 is an Acti9 iCV40H combined residual-current circuit breaker (RCBO) — one module wide, 1P+N, rated 10 A with a C curve. It integrates overcurrent protection (thermal-magnetic trip) and earth-leakage protection at 300 mA sensitivity into a single DIN-rail unit.
The 10 A rated current (In) sets the continuous load capacity; the C curve (magnetic trip 5–10 x In) tolerates moderate inrush from motor or lighting loads. The 300 mA earth-leakage threshold is for equipment protection, not personnel.
Clip-on mount to standard DIN rail. Neutral is on the left, phase on the right. Tunnel terminals accept 1–16 mm² rigid or 1–10 mm² flexible; strip 14 mm, torque to 2 N·m.
Listed as current production. The Acti9 range is Schneider's standard modular DIN-rail family; the iCV40H variant is a common RCBO for distribution outgoing circuits.
