The A9F54332 is a three-pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H family, engineered for multi-standard low-voltage distribution systems. It protects three poles simultaneously, carries a 32 A rating, and employs a C‑curve trip characteristic that balances reliable overload protection with tolerance of moderate inrush currents—ideal for lighting circuits, control panels, and small motor feeders. The device delivers a rated short-circuit 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, offering flexibility across commercial, light‑industrial, and residential projects. User‑oriented features include the VisiTrip indicator, which instantly identifies the faulted pole to reduce troubleshooting time, and the VisiSafe green strip, which provides visual confirmation that the contacts are physically open for safe downstream maintenance. 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, it is a robust, space‑saving solution for demanding distribution boards.
