The A9F74263 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60N range, rated at 63 A with a C‑curve tripping characteristic (magnetic threshold at 8 × In). This 2‑pole device is engineered to protect both lines in single‑phase AC or DC circuits, ensuring simultaneous disconnection of phase and neutral for complete isolation and enhanced safety in heavy‑duty distribution applications – 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 workhorse for a broad spectrum of demanding installations. Delivering a robust ultimate breaking capacity of 20 kA at 220‑240 V AC (per IEC 60947‑2) and 6 kA at 400 V AC (per IEC 60898‑1), this MCB ensures reliable fault clearing in the most challenging industrial and commercial environments. It is dual‑certified to both industrial and residential standards, providing flexibility across project types. The breaker incorporates the intuitive VisiTrip indicator, which instantly identifies the tripped pole for rapid 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, guarantees 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 valuable panel space, while the terminals accept rigid conductors up to 35 mm² and flexible up to 25 mm² with a 3.5 N·m tightening 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.
