The Schneider Electric Acti9 iC60H A9F53340 is a three-pole miniature circuit breaker designed for low-voltage distribution systems. It provides reliable protection against short circuits and overloads with a 40 A rating and a B-type thermal-magnetic trip curve. The breaker delivers a short-circuit breaking capacity of 30 kA at 220–240 V AC according to EN/IEC 60947-2 and 10,000 A at 415 V AC according to EN/IEC 60898-1, making it suitable for both industrial and residential applications. Its double tunnel terminals ensure secure connections. The VisiTrip indicator helps maintenance personnel quickly locate the faulted circuit, while the VisiSafe green strip confirms that the contacts are physically open for safe downstream work. A fast-closing mechanism independent of the toggle extends the service life, rated for 10,000 electrical and 20,000 mechanical cycles. The device has a rated insulation voltage of 500 V AC and a limitation class of 3, which helps reduce downstream protection costs. It mounts on a 35 mm DIN rail, occupies six 9 mm pitches (54 mm width), and measures 85 mm × 54 mm × 78.5 mm with a net weight of 0.375 kg. It offers IP20 terminal protection, operates from -35 °C to +70 °C, and comes in white (RAL9003). With pollution degree 3 and a 54% recyclability potential, it is a durable and sustainable solution for three-phase circuits.
