The A9F54306 is a three-pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H range, designed to deliver reliable short-circuit and overload protection in three-phase AC and DC distribution systems. Rated at 6 A with a C‑curve trip profile, it balances precise overload protection with tolerance of moderate inrush currents, making it suitable for lighting circuits, control panels, and small motor feeders. The device offers a high ultimate breaking capacity of 30 kA at 220–240 V AC (per EN/IEC 60947‑2) and 10 kA at 415 V AC (per EN/IEC 60898‑1), and it carries dual certification to both industrial and residential standards, ensuring broad application flexibility. Its VisiTrip indicator window quickly reveals the faulted pole to minimise troubleshooting downtime, while the VisiSafe green strip provides a clear visual guarantee that the contacts are physically open, allowing safe downstream maintenance. A fast-closing mechanism, independent of the toggle handle, contributes to an extended service life with 10,000 electrical and 20,000 mechanical cycles. The breaker occupies six 9 mm pitches (54 mm width) and mounts on a standard DIN rail, offering IP20 terminal protection (IP40 when enclosed). With an operating temperature range of -35 °C to +70 °C and a compact 54 × 85 × 78.5 mm footprint, it is a robust, space-saving solution for commercial, light-industrial, and residential distribution boards.
