The A9F75106 is a 6‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, engineered with a D‑curve tripping characteristic (magnetic threshold at 12 × In). The D‑curve is purpose‑built for circuits with significant inrush currents – such as small transformers, solenoid valves, motor starters, and capacitive loads – where B‑ or C‑curve breakers would be susceptible to nuisance tripping. This MCB provides a rated ultimate breaking capacity of 10 kA at 220‑240 V AC under the industrial standard EN/IEC 60947‑2 (with higher values at lower voltages) and 6 kA at 230 V AC per the residential norm EN/IEC 60898‑1, ensuring dependable fault interruption in high‑fault‑current environments. Certified to both standards, it offers flexible deployment across industrial control panels, commercial distribution boards, and specialised residential applications. Designed with Class‑2 insulation for enhanced operator safety, the breaker also offers full coordination with Acti 9 RCDs and Compact NSX MCCBs, simplifying system integration. The device incorporates the proven VisiTrip fault‑finder window, which instantly highlights the tripped pole to shorten diagnostic time, and the VisiSafe green strip that delivers unmistakable visual confirmation 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 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 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 a 54% recyclability rate and a total lifecycle carbon footprint of only 8 kg CO₂ eq., reflecting Schneider Electric’s eco‑design philosophy.
