The Schneider Electric A9DGB632 is an Acti9 iCV40 residual current circuit breaker with overcurrent protection (RCBO) rated at 32 A, B curve, with integrated 100 mA earth-leakage protection.
The 100 mA sensitivity is higher than the 30 mA typically specified for personal shock protection; it is selected where nuisance tripping from leakage in long cable runs or equipment with natural leakage (heaters, motors with filters) would otherwise cause unwanted downtime. The thermal-magnetic trip unit provides inverse-time overload protection and instantaneous short-circuit response in one package.
Neutral is on the left (1P+N configuration). Tunnel terminals accept 1–16 mm² rigid or 1–10 mm² flexible cable; tighten to 2 N·m. The 9 mm phase-to-neutral pitch matches the Acti9 busbar system for daisy-chaining outgoing circuits in a distribution board.
