The A9F54316 is a three-pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H range, engineered to provide dependable overcurrent protection in three-phase AC and DC distribution systems. With a 16 A rating and a C‑curve trip characteristic, it delivers a balanced response between overload protection and tolerance of moderate inrush currents, making it well suited 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 holds dual certification to both industrial and residential standards, giving designers flexibility across mixed‑use projects. Key user‑focused features include the VisiTrip fault indicator, which immediately reveals the faulted pole to shorten maintenance downtime, and the VisiSafe green strip, which provides a clear visual guarantee that the contacts are physically open for safe downstream work. A fast‑closing mechanism, independent of manual operation, contributes to an extended service life, with electrical endurance rated at 10,000 cycles and mechanical endurance at 20,000 cycles. The breaker occupies six 9 mm pitches (54 mm width) and clips onto a standard DIN rail, while offering IP20 terminal protection. Its operating temperature range spans -35 °C to +70 °C, and it is finished in white (RAL9003). With a compact 54 × 85 × 78.5 mm footprint and a weight of 0.375 kg, this MCB is a robust, space‑saving solution for commercial, light‑industrial, and residential distribution boards.
