The A9F95104 is a 4‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60L series, distinguished by its K‑curve tripping characteristic (magnetic threshold at 12 × In). The K‑curve is specifically tailored for circuits with pronounced inrush currents – such as transformers, solenoid valves, motor starters, and capacitive loads – where conventional B‑ or C‑curves would be prone to nuisance tripping. Rated at 4 A, this MCB delivers an outstanding ultimate breaking capacity of 100 kA at 220‑240 V AC under the industrial EN/IEC 60947‑2 standard (with derated values for other voltages) and 15 kA at 230 V AC per the residential EN/IEC 60898‑1 norm, ensuring robust fault interruption even in the most demanding high‑fault‑current scenarios. It is certified to both standards, making it a flexible choice for industrial automation, commercial control panels, and specialised residential installations. The breaker integrates the intuitive VisiTrip fault‑finder window, which instantly pinpoints the tripped pole to accelerate troubleshooting, and the VisiSafe green strip that provides clear visual evidence of contact separation – a critical safety feature for maintenance operations. Its quick‑make/quick‑break mechanism, independent of toggle position, guarantees consistent 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 halogen‑free plastics and PVC‑free materials, achieving a 54% recyclability rate and a total lifecycle carbon footprint of 14 kg CO₂ eq.
