The A9F74232 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, rated at 32 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). Designed to protect both poles simultaneously, this 2‑pole device ensures complete disconnection of phase and neutral in single‑phase AC systems or both lines in DC installations, delivering superior isolation and safety for general‑purpose distribution circuits – including lighting networks, power outlets, small motor feeders, and control panels in commercial, industrial, and residential environments. The C‑curve offers a well‑balanced response between overload protection and tolerance of moderate inrush currents, making it a versatile and reliable choice across a broad spectrum of applications. This MCB provides a robust ultimate breaking capacity of 20 kA at 220‑240 V AC (per IEC 60947‑2) and 6 kA at 400 V AC (per IEC 60898‑1), ensuring dependable fault clearing in demanding installations. It is dual‑certified to both industrial and residential standards, offering flexibility across project types. The breaker features the intuitive VisiTrip indicator, which instantly identifies the tripped pole for fast fault diagnosis, and the VisiSafe green strip that provides clear visual proof of contact opening – a critical safety feature for maintenance work. Its quick‑make/quick‑break mechanism, independent of handle position, ensures consistent performance over 10,000 electrical and 20,000 mechanical cycles. With a compact 36 mm width (4 modular pitches) and DIN‑rail mounting, it saves panel space, while the terminals accept rigid conductors up to 35 mm² and flexible up to 25 mm² with a 3.5 N·m tightening torque. Operating reliably from -35 °C to +70 °C, this MCB is built with halogen‑free plastics and PVC‑free materials, achieving 54% recyclability and a total lifecycle carbon footprint of 33 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, high‑performance power distribution.
