The Schneider Electric A9D44610 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — one module wide, combining a 10 A thermal-magnetic MCB and a 300 mA earth-leakage trip in a single 1P+N unit. The C-curve (magnetic trip 5...10 x In) suits it for circuits with moderate inrush — lighting banks, socket outlets, small motor loads — where a B-curve would nuisance-trip on startup but a D-curve would delay too long for cable protection.
Terminals accept 1...16 mm² rigid or 1...10 mm² flexible (with or without ferrule); strip 15 mm and torque to 2 N·m. The 9 mm pitch between phase and neutral matches the Acti9 busbar system for clean distribution wiring.
Listed as current production (active lifecycle). The A9D44610 is a standard catalogue item in the Acti9 range, widely specified for new installations and replacement spares.
