The A9F75320 is a three-pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N range, designed to provide dependable overcurrent protection in three-phase AC and DC distribution systems. Rated at 20 A with a D‑curve trip response, it is particularly suited to loads with high inrush currents, such as small motors, transformers, solenoid valves, and capacitive equipment, where lower‑curve devices may trip unnecessarily. The breaker offers a short‑circuit breaking capacity of 20 kA at 220–240 V AC under EN/IEC 60947‑2 and 6 kA at 400 V AC under EN/IEC 60898‑1, and it is certified to both industrial and residential standards. Its VisiTrip indicator quickly identifies the faulted pole to reduce maintenance time, while the VisiSafe green strip confirms physical contact opening for safe downstream work. A fast‑closing mechanism, independent of the toggle, helps extend service life, with 10,000 electrical and 20,000 mechanical cycles. The unit occupies six 9 mm pitches (54 mm width) and mounts on DIN rail, with IP20 terminal protection (IP40 when enclosed). It operates from -35 °C to +70 °C and is finished in white (RAL9003). Weighing 0.375 kg, it is a compact, robust solution for commercial and industrial three‑phase boards.
