Schneider Electric's Acti9 iC60N A9F74340 is a three-pole miniature circuit breaker (MCB) intended for low-voltage distribution systems. It is rated 40 A and uses a C-characteristic thermal-magnetic trip unit, making it suitable for circuits with moderate inrush currents. The breaker provides a short-circuit breaking capacity of 20 kA at 220–240 V AC according to EN/IEC 60947-2 and 6,000 A at 400 V AC according to EN/IEC 60898-1, while also supporting DC applications up to 180 V. It complies with both industrial and residential standards. Key features include the VisiTrip indicator, which helps locate the faulted circuit quickly, and the VisiSafe green strip, which confirms that contacts are physically open for safe downstream maintenance. Its fast-closing mechanism, independent of the toggle, extends service life to 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 six 9 mm pitches (54 mm wide), and measures 85 × 54 × 78.5 mm with a net weight of 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 solution for three-phase circuits.
