The A9F94240 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60L family, rated at 40 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve provides a well‑balanced response between overload protection and tolerance of moderate inrush currents, making it an ideal choice for general‑purpose distribution circuits – including lighting networks, socket outlets, small motor feeders, and control panels in commercial, industrial, and residential settings. With both poles protected, this 2‑pole device ensures simultaneous disconnection of phase and neutral in single‑phase AC systems or both lines in DC installations, delivering complete isolation and enhanced safety. This MCB offers a robust ultimate breaking capacity of 36 kA at 220‑240 V AC (per IEC 60947‑2) and 15 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, providing 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 PVC‑free materials and achieves 54% recyclability, though it contains halogen above thresholds. Its total lifecycle carbon footprint is quantified at 41 kg CO₂ eq., reflecting Schneider Electric’s commitment to transparent environmental reporting.
