The A9F77125 is a 25‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, featuring a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve delivers a balanced protection profile – offering reliable overload and short‑circuit protection while tolerating moderate inrush currents – making it a popular choice for general‑purpose distribution circuits, including lighting, receptacles, small power tools, and HVAC control panels in commercial, industrial, and residential applications. This MCB provides a rated ultimate breaking capacity of 10 kA at 220‑240 V AC under the industrial EN/IEC 60947‑2 standard, and 6 kA at 230 V AC per the residential EN/IEC 60898‑1 norm, ensuring dependable fault clearance in diverse installations. It is dual‑certified to both standards, allowing seamless integration into projects that require cross‑standard acceptance. The breaker incorporates the intuitive VisiTrip fault indicator window, which instantly highlights the tripped pole to shorten troubleshooting time, and the VisiSafe green strip that delivers clear visual confirmation of contact opening – a critical safety feature for maintenance operations. Its quick‑make/quick‑break mechanism, independent of handle position, guarantees consistent switching performance over 10,000 electrical and 20,000 mechanical cycles. With a compact 18 mm width (2 modular pitches) and DIN‑rail clip‑on mounting, it saves 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. The device offers IP20 terminal protection and IP40 when enclosed, operates reliably from -35 °C to +70 °C, and is built with PVC‑free materials, though it contains halogen above thresholds. Achieving a 54% recyclability rate and a total lifecycle carbon footprint of 17 kg CO₂ eq., this MCB aligns with Schneider Electric’s sustainability objectives.
