The Schneider Electric Acti9 iC60H A9F84404 is a four-pole miniature circuit breaker designed for low-voltage distribution systems. It is rated 4 A and uses a C-characteristic thermal-magnetic trip unit, making it suitable for circuits with moderate inrush currents. The device provides short-circuit breaking capacities of 70 kA at 220–240 V AC under EN/IEC 60947-2 and 10,000 A at 400 V AC under EN/IEC 60898-1. It meets both industrial and residential standards. Double tunnel terminals help ensure secure wiring. The VisiTrip indicator speeds up fault location, 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 breaker 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 for four-pole protection.
