The A9F94202 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60L series, featuring a C‑curve tripping characteristic (magnetic threshold at 8 × In). This 2‑pole device is designed to protect both lines in single‑phase AC or DC circuits, ensuring simultaneous disconnection of phase and neutral for complete isolation and enhanced safety in sensitive applications – including control transformers, electronic power supplies, instrumentation, signal lines, and PLC input/output modules, where even minor overcurrents can damage costly components. The C‑curve offers a balanced response between overload protection and tolerance of moderate inrush currents, making it a versatile and reliable choice across a broad spectrum of applications. Despite its modest 2 A rating, this MCB delivers an exceptional ultimate breaking capacity of 100 kA at 220‑240 V AC (per IEC 60947‑2) – a performance level rarely seen in low‑current devices – and 15 kA at 400 V AC (per IEC 60898‑1), guaranteeing reliable fault clearing even in high‑fault‑current industrial environments. It is dual‑certified to both industrial and residential standards, offering flexible deployment across control panels, distribution boards, and specialised equipment protection. 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 23 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, high‑performance power distribution.
