The A9F74225 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, rated at 25 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). As a 2‑pole device protecting both lines, it ensures simultaneous disconnection of phase and neutral in single‑phase AC systems or both poles in DC installations, providing complete isolation and enhanced safety for general‑purpose distribution circuits – including lighting banks, socket 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 rated ultimate breaking capacity of 10 kA at 380‑415 V AC (IEC 60947‑2) and 6 kA at 400 V AC (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 double‑tunnel terminals accept conductors up to 25 mm² (rigid) and 16 mm² (flexible) with a 2 N·m 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 35 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, high‑performance power distribution.
