The A9F53206 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, rated at 6 A with a B‑curve tripping characteristic (magnetic threshold at 4 × In). As a 2‑pole device protecting both lines simultaneously, it ensures complete disconnection of phase and neutral in single‑phase AC systems or both poles in DC installations, delivering superior isolation and safety for sensitive resistive loads, lighting circuits, and general‑purpose distribution. The B‑curve is specifically optimised for circuits with minimal inrush currents, providing precise overload protection without nuisance tripping. This MCB offers a robust ultimate breaking capacity of 30 kA at 220‑240 V AC (per IEC 60947‑2) and 10 kA at 415 V AC (per IEC 60898‑1), guaranteeing reliable fault clearing in demanding industrial and commercial environments. Dual‑certified to both industrial and residential standards, it provides flexibility across diverse applications. The breaker features the intuitive VisiTrip indicator, which instantly identifies the tripped pole for fast fault diagnosis, and the VisiSafe green strip that gives clear visual proof of contact opening – a critical safety feature for maintenance crews. 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 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 16 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, high‑performance power distribution.
