The A9F54225 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H range, rated at 25 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). Designed to protect both poles simultaneously, this 2‑pole device guarantees complete disconnection of phase and neutral in single‑phase AC systems or both lines in DC applications, delivering enhanced isolation and safety for general‑purpose distribution circuits – including lighting banks, socket outlets, small motor feeders, and control panels in commercial, industrial, and residential settings. The C‑curve offers a well‑balanced response between overload protection and tolerance of moderate inrush currents, making it a reliable choice for a wide variety of loads. This MCB provides a robust ultimate breaking capacity of 30 kA at 220‑240 V AC (IEC 60947‑2) and 10 kA at 415 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 integrates the intuitive VisiTrip indicator, which instantly identifies the tripped pole for rapid 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.
