The Schneider Electric Acti9 iC60N A9F74325 is a three-pole miniature circuit breaker engineered for low-voltage distribution boards. It carries a 25 A rating and a C-characteristic thermal-magnetic trip unit, making it suitable for circuits with moderate inrush currents. The device provides a short-circuit breaking capacity of up to 20 kA at 220–240 V AC under EN/IEC 60947-2 and 6,000 A at 400 V AC under EN/IEC 60898-1, and it meets both industrial and residential standards. It protects against overloads and short circuits. The VisiTrip indicator helps maintenance personnel locate the faulted circuit quickly, while the VisiSafe green strip confirms that contacts are physically open for safe downstream work. Its fast-closing mechanism, independent of the toggle, extends service life to 10,000 electrical and 20,000 mechanical cycles. The 500 V AC rated insulation and Class 3 limitation help reduce downstream protection costs. The breaker clips onto a 35 mm DIN rail and occupies six 9 mm pitches (54 mm wide). It measures 85 × 54 × 78.5 mm and weighs 0.375 kg. It offers IP20 terminal protection (IP40 when enclosed), operates from -35 °C to +70 °C, and comes in white (RAL9003). With pollution degree 3, overvoltage category IV, and a 54% recyclability potential, it is a durable and sustainable choice for three-phase circuits.
