The Schneider Electric A9D01610 is an Acti9 iDPN N Vigi residual-current circuit breaker (RCBO) — a 1P+N device combining overcurrent protection and earth-leakage detection in a single 36 mm wide module. Rated at 10 A with a C-curve (magnetic trip 5–10 × In), it is built for final-subcircuit protection on 50 Hz AC networks. The integrated 30 mA earth-leakage sensitivity covers personnel protection (additional shock-hazard mitigation) per EN/IEC 61009-2-1. Breaking capacity is 6000 A Icn at 110 V AC, which is standard for residential and light-commercial distribution boards — adequate for fault currents typical at the outgoer position. The thermal-magnetic trip unit handles sustained overloads and short-circuits; the residual-current module adds ground-fault detection without needing a separate RCCB upstream.
Clip-on mounting to a DIN rail, 4 modules of 9 mm pitch (36 mm total width). Neutral is on the left; phase and neutral connections are single terminals top and bottom, accepting 1–16 mm² rigid or 1–10 mm² flexible. Tightening torque 2 N·m; strip length 15 mm. The device occupies one standard MCB/RCBO slot in a modular enclosure. IP20 on the terminals (finger-safe), IP40 on the modular enclosure face — suitable for dry indoor distribution boards. Tropicalisation class 2 per IEC 60068-1 means it withstands 95 % RH at 55 °C without condensation damage.
