The Schneider Electric Acti9 iC60H A9F55463 is a four-pole miniature circuit breaker designed for low-voltage distribution systems. It features double tunnel terminals and a 63 A rated current with a D-characteristic thermal-magnetic trip unit, making it suitable for circuits with high inrush currents. The breaker delivers a short-circuit breaking capacity of 30 kA at 220–240 V AC under EN/IEC 60947-2 and 10,000 A at 415 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 VisiTrip fault indication, VisiSafe contact-position verification, and a fast-closing mechanism that 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 width), 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 circuits.
