The A9F94104 is a 4‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60L series, equipped with a C‑curve tripping characteristic (magnetic threshold at 8 × In). This C‑curve delivers a well‑balanced response between thermal overload protection and tolerance of moderate inrush currents, making it a flexible solution for general‑purpose distribution – including lighting circuits, socket outlets, control panels, and small power feeders – across commercial, industrial, and residential installations. What truly elevates this model is its outstanding ultimate breaking capacity: rated at 100 kA at 220‑240 V AC under the EN/IEC 60947‑2 industrial standard, and 15 kA at 230 V AC per the EN/IEC 60898‑1 residential norm, ensuring robust fault clearing even in high‑fault‑current environments. This MCB complies with both standards, offering seamless integration across mixed‑use projects. The device incorporates the intuitive VisiTrip fault‑finder window, which visually pinpoints the tripped pole to accelerate troubleshooting, and the VisiSafe green strip that provides unmistakable visual confirmation of contact separation – a critical safety feature for downstream maintenance. Its quick‑make/quick‑break mechanism, independent of the toggle handle, 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 optimises panel space. The double‑tunnel terminals accept rigid conductors up to 25 mm² and flexible up to 16 mm², with a 2 N·m torque. The device offers IP20 protection at the terminals and IP40 when enclosed, operating from -35 °C to +70 °C. Sustainability features include a halogen‑free status (plastic parts) and PVC‑free construction, with a 54% recyclability rate and a total lifecycle carbon footprint of 14 kg CO₂ eq., all transparently disclosed in line with Schneider Electric’s environmental commitments.
