The Schneider Electric Acti9 iC60N A9F74402 is a four-pole miniature circuit breaker engineered for low-voltage distribution boards. It is rated 2 A and features a C-curve thermal-magnetic trip unit, so it responds to overloads and short circuits in circuits with moderate inrush currents. The breaker provides short-circuit breaking capacities of 50 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. Double tunnel terminals help ensure secure wiring. The VisiTrip indicator helps maintenance staff locate the faulted circuit quickly, while the VisiSafe green strip confirms that contacts are physically open for safe downstream work. A fast-closing mechanism, independent of the toggle, contributes to a long service life, rated for 10,000 electrical and 20,000 mechanical cycles. The device has a 500 V AC rated insulation voltage and Class 3 limitation, which helps reduce downstream protection costs. It clips onto a 35 mm DIN rail, occupies eight 9 mm pitches (72 mm wide), and measures 85 × 72 × 78.5 mm with a net weight of 0.5 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.
