The Schneider Electric A9F94402 is a four-pole miniature circuit breaker from the Acti9 iC60L series, designed for low-voltage distribution systems. It is rated 2 A with a C-characteristic thermal-magnetic trip unit, providing protection against short circuits and overload currents. The device delivers a short-circuit breaking capacity of up to 100 kA at 380–415 V AC under EN/IEC 60947-2 and 15,000 A at 400 V AC under EN/IEC 60898-1, and it complies with both industrial and residential standards. Its VisiTrip indicator helps maintenance staff identify the faulted circuit quickly, while the VisiSafe green strip confirms physical contact opening for safe downstream work. A fast-closing mechanism, independent of manual operation, contributes to a long service life, rated for 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 mounts on 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, halogen-free plastic parts, PVC-free construction, and a 54% recyclability potential, it supports durable and sustainable installations.
