The A9F75102 is a 2‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, equipped with a D‑curve tripping characteristic (magnetic threshold at 12 × In). The D‑curve is specifically designed for circuits that experience substantial inrush currents – such as small transformers, solenoid valves, capacitive loads, and motor starters – where lower‑curve breakers (B or C) would be prone to nuisance tripping. Despite its low 2 A rating, this MCB delivers an outstanding ultimate breaking capacity of 50 kA at 220‑240 V AC under the industrial standard EN/IEC 60947‑2, and 6 kA at 230 V AC per the residential norm EN/IEC 60898‑1, ensuring reliable fault interruption even in high‑fault‑current environments. Certified to both standards, it offers flexible deployment across industrial control panels, commercial distribution boards, and specialised residential applications. The breaker incorporates the proven VisiTrip fault‑finder window, which visually pinpoints the tripped pole to shorten diagnostic time, and the VisiSafe green strip that provides clear evidence of contact separation – a critical safety feature for maintenance crews. Its quick‑make/quick‑break mechanism, independent of toggle 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 mounting, it saves 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, and the device offers IP20 terminal protection and IP40 when enclosed, operating reliably from -35 °C to +70 °C. Built with halogen‑free plastics and PVC‑free materials, it achieves 54% recyclability and a total lifecycle carbon footprint of 11 kg CO₂ eq., reflecting Schneider Electric’s eco‑design approach.
