The Schneider Electric A9D44632 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — one module wide, combining a 32 A thermal-magnetic MCB and a 300 mA earth-leakage trip in a single 1P+N unit.
The 32 A rated current (In) and C-curve magnetic trip (5–10 × In) suit general-purpose socket-outlet and lighting circuits where inrush from small motors or capacitive loads is moderate — the C-curve holds through the start-up surge without nuisance tripping. The integrated 300 mA earth-leakage protection is a standard sensitivity for socket-outlet circuits where 30 mA is not required (e.g., general-purpose, not wet areas or construction-site supplies). The RCBO trips on both overcurrent and residual current, so one device replaces a separate MCB + RCCB combination, saving a DIN module.
Terminals accept 1–16 mm² solid or 1–10 mm² flexible (with or without ferrule); strip length 15 mm, tightening torque 2 N·m.
