The Schneider Electric A9D02610 is an Acti9 iDPN Vigi combined overcurrent and earth-leakage circuit breaker (RCBO) rated 10 A with a C-curve magnetic trip (5–10 × In) and 10 mA residual-current sensitivity. It protects a single-phase final subcircuit against overload, short-circuit, and earth fault in one 36 mm wide module — neutral left, 1P+N poles, clip-on DIN-rail mount. The 6 kA Icn breaking capacity at 230…240 V AC (EN/IEC 61009-2-1) covers most residential and light commercial distribution boards; the 10 mA sensitivity is specified for circuits where additional protection against electric shock is required, such as socket-outlets in wet areas or circuits supplying hand-held equipment.
Ratings that govern the selection
The 10 A rated current and C-curve mean the breaker holds 10 A continuously and trips magnetically between 50 A and 100 A — typical for mixed resistive-inductive loads like lighting, small appliances, and general-purpose socket circuits. The 10 mA earth-leakage sensitivity is tighter than the more common 30 mA; it is chosen where higher touch-voltage protection is needed but must be coordinated with the installation's earth-loop impedance.
Clip-on mounting to DIN rail, 36 mm width — occupies 4 × 9 mm pitches. IP20 enclosure (IP40 in modular enclosure). Terminals accept 1…16 mm² rigid, 1…10 mm² flexible, or 1…10 mm² flexible with ferrule; tightening torque 2 N·m; strip length 15 mm.
