The A9F53216 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, rated at 16 A with a B‑curve tripping characteristic (magnetic threshold at 4 × In). The B‑curve is specifically designed for circuits with minimal or negligible inrush currents – such as lighting, resistive heating, and general‑purpose distribution – providing precise overload and short‑circuit protection without nuisance tripping. As a 2‑pole device with both poles protected, it guarantees simultaneous disconnection of both lines, delivering complete isolation and enhanced safety for single‑phase AC or DC installations. 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), ensuring reliable fault clearing in demanding industrial and commercial environments. It is dual‑certified to both industrial and residential standards, offering 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 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 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 28 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, high‑performance power distribution.
