The A9F77206 is a 6‑ampere, double‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, featuring a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve offers an optimal balance between overload protection and tolerance of moderate inrush currents, making it a versatile solution for general‑purpose distribution – including lighting circuits, socket outlets, small power feeders, and control panels in commercial, industrial, and residential installations. With both poles protected, this 2‑pole device ensures simultaneous disconnection of both lines in single‑phase AC systems or DC applications, significantly enhancing safety and isolation integrity. This MCB provides a rated ultimate breaking capacity of 20 kA at 220‑240 V AC under the industrial standard EN/IEC 60947‑2, and 6 kA at 400 V AC per the residential norm EN/IEC 60898‑1, ensuring reliable fault interruption across a broad range of applications. Certified to both standards, it offers flexible integration into mixed‑use projects. Designed with Class‑2 insulation for superior operator protection, the breaker also coordinates fully with Acti 9 RCDs and Compact NSX MCCBs, simplifying system design. The device incorporates the intuitive VisiTrip fault‑finder window, which instantly identifies the tripped pole to accelerate troubleshooting, and the VisiSafe green strip that delivers unmistakable visual confirmation of contact opening – a critical safety check for maintenance personnel. Its quick‑make/quick‑break mechanism, independent of handle position, ensures consistent switching performance over 10,000 electrical and 20,000 mechanical cycles. Despite its 6 A rating, the breaker maintains a compact 36 mm width (4 modular pitches) and clips onto DIN rails, saving valuable panel space. The double‑tunnel terminals accept rigid conductors up to 25 mm² and flexible up to 16 mm² with a 2 N·m tightening torque, and the device offers IP20 terminal protection and IP40 when enclosed. Operating reliably from -35 °C to +70 °C, it is built with PVC‑free materials, though it contains halogen above thresholds. Achieving a 54% recyclability rate and a total lifecycle carbon footprint of 16 kg CO₂ eq., this MCB aligns with Schneider Electric’s sustainable energy management objectives.
