The A9F54301 is a three-pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, engineered to deliver multi-standard protection in low-voltage AC and DC distribution systems. Rated at 1 A with a C‑curve trip response, it is tailored for circuits that require precise overload protection with moderate tolerance to inrush currents—such as control circuits, instrumentation, and sensitive electronic loads. The device achieves an exceptional short‑circuit breaking capacity of up to 70 kA at 220–240 V AC under the industrial EN/IEC 60947‑2 standard, and 10 kA at 415 V AC under the residential EN/IEC 60898‑1 standard, while also covering DC applications up to 180 V. Dual certification ensures seamless integration into both industrial panels and residential boards. Its VisiTrip indicator window instantly identifies the faulted pole to reduce troubleshooting downtime, and the VisiSafe green strip provides clear visual confirmation that the contacts are physically open for safe downstream maintenance. A fast‑closing mechanism, independent of the toggle, helps extend service life, with 10,000 electrical and 20,000 mechanical cycles. The breaker occupies six 9 mm pitches (54 mm width) and clips onto a DIN rail, offering IP20 terminal protection and operating from -35 °C to +70 °C. Finished in white (RAL9003) and weighing 0.375 kg, it is a robust, compact solution for demanding three‑phase applications.
