The A9F84210 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, rated at 10 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). As a 2‑pole device with both poles protected, it guarantees simultaneous disconnection of phase and neutral in single‑phase AC systems or both lines in DC installations, providing complete isolation and enhanced safety for general‑purpose distribution circuits – including lighting networks, socket outlets, small motor feeders, and control panels in commercial, industrial, and residential environments. The C‑curve offers a well‑balanced response between overload protection and tolerance of moderate inrush currents, making it a versatile and reliable choice across a broad spectrum of applications. This MCB delivers a robust ultimate breaking capacity of 30 kA at 220‑240 V AC (per IEC 60947‑2) and 10 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, offering 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 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 PVC‑free materials and is silicone‑free, achieving 54% recyclability, though it contains halogen above thresholds.
