The A9F89263 is a high‑capacity two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, rated at 63 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). Designed to protect both poles simultaneously, this 2‑pole device ensures complete disconnection of phase and neutral in single‑phase AC systems or both lines in DC installations, delivering superior isolation and safety for heavy‑duty distribution circuits – including large lighting banks, power feeders, HVAC equipment, motor control panels, and industrial distribution boards. The C‑curve offers a well‑balanced response between overload protection and tolerance of moderate inrush currents, making it a versatile choice for a wide range of demanding 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 reliable fault clearing in the most demanding industrial and commercial environments. 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 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 terminals accept rigid conductors up to 35 mm² and flexible up to 25 mm² with a 3.5 N·m torque. Operating reliably from -35 °C to +70 °C, this MCB is built with PVC‑free materials and achieves 54% recyclability, though it contains halogen above thresholds. Its total lifecycle carbon footprint is quantified at 63 kg CO₂ eq., reflecting Schneider Electric’s transparent environmental reporting.
