The A9F76225 is a 25‑ampere, double‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60N range, featuring a B‑curve tripping characteristic (magnetic threshold at 4 × In). The B‑curve is specifically tailored for circuits with minimal or negligible inrush currents – such as lighting, resistive heating loads, and general‑purpose distribution – where precise overload protection is paramount and nuisance tripping must be avoided. As a 2‑pole device with both poles protected, it ensures simultaneous disconnection of both lines in single‑phase AC systems or DC applications, providing enhanced safety and isolation integrity. This MCB delivers a robust ultimate breaking capacity of 20 kA at 220‑240 V AC under the industrial standard EN/IEC 60947‑2 (with higher ratings at lower voltages) and 6 kA at 400 V AC per the residential norm EN/IEC 60898‑1, ensuring reliable fault interruption in a wide range of commercial, industrial, and residential installations. 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 architecture. The device features 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 performance over 10,000 electrical and 20,000 mechanical cycles. Despite its 25 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 halogen‑free plastics and PVC‑free materials, achieving a 54% recyclability rate and a total lifecycle carbon footprint of 35 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, safe energy distribution.
