The A9F53202 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H family, rated at 2 A with a B‑curve tripping characteristic (magnetic threshold at 4 × In). Designed for circuits with minimal inrush currents – such as resistive heating, lighting banks, and sensitive electronic loads – the B‑curve delivers precise overload protection without nuisance tripping. As a 2‑pole device with both poles protected, it ensures complete disconnection of both lines in single‑phase AC or DC installations, providing enhanced safety and full isolation. What truly distinguishes this model is its exceptional ultimate breaking capacity of 70 kA at 220‑240 V AC (per IEC 60947‑2) – a remarkable performance level typically reserved for much larger breakers – and 10 kA at 415 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.
