The Schneider Electric Acti9 iC60N A9F77450 is a four-pole miniature circuit breaker (MCB) designed for low-voltage distribution systems. It provides a 50 A rated current and a C-characteristic thermal-magnetic trip curve, making it suitable for circuits with moderate inrush currents. The breaker offers a short-circuit breaking capacity of up to 10 kA at 220–240 V AC under EN/IEC 60947-2 and 6,000 A at 400 V AC under EN/IEC 60898-1, while also covering DC applications up to 250 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. The 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 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.
