The A9F75120 is a 20‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, featuring a D‑curve tripping characteristic (magnetic threshold at 12 × In). This D‑curve design makes it the go‑to choice for circuits with significant inrush currents – think motor starters, compressors, welding equipment, and transformer feeders – where standard B‑ or C‑curve breakers would trip unnecessarily. As part of the iC60N family, this MCB delivers a robust 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 for residential installations per EN/IEC 60898‑1, ensuring reliable protection across a broad spectrum of applications. The device incorporates the well‑regarded VisiTrip fault‑finder, which visually highlights the tripped pole to accelerate fault diagnosis, and the VisiSafe green indicator that provides unequivocal proof of contact separation – an indispensable safety check before any maintenance work. Its quick‑make/quick‑break mechanism, fully independent of the toggle position, guarantees consistent switching performance and contributes to a long service life of 10,000 electrical and 20,000 mechanical cycles. The compact 18 mm width (2 modular pitches) and DIN‑rail clip‑on mounting optimise panel space, while the double‑tunnel terminals accept rigid conductors up to 25 mm². Notably, this model offers IP40 protection when housed in a modular enclosure (in addition to IP20 at the terminals), enhancing its suitability for demanding environments. Operating flawlessly from -35 °C to +70 °C, it also meets stringent sustainability criteria: halogen‑free plastics, PVC‑free construction, a 54% recyclability rate, and a total lifecycle carbon footprint of 14 kg CO₂ eq., all backed by Schneider Electric’s transparent environmental disclosure.
