The A9F73106 is a 6‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, featuring a B‑curve tripping characteristic (magnetic threshold at 4 × In). The B‑curve is specifically engineered for circuits with negligible or very low inrush currents – typical of lighting banks, resistive heating elements, and general‑purpose socket outlets – delivering precise overload and short‑circuit protection without nuisance tripping. Rated with an ultimate breaking capacity of 10 kA at 220‑240 V AC per the industrial EN/IEC 60947‑2 standard and 6 kA at 230 V AC under the residential EN/IEC 60898‑1 norm, this MCB offers reliable fault clearance across diverse installation environments. It meets both standards, making it equally suitable for commercial distribution boards, industrial control panels, and domestic consumer units. The breaker incorporates the field‑proven VisiTrip indicator window, which instantly flags the tripped pole to minimise diagnostic downtime, and the VisiSafe green strip that provides positive visual evidence of contact separation – a crucial safety check for maintenance staff. 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 enclosure 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 protection at the terminals and IP40 when housed in a modular enclosure, operates flawlessly from -35 °C to +70 °C, and is built with halogen‑free plastics, PVC‑free materials, and a 54% recyclability rate – all contributing to a total lifecycle carbon footprint of only 8 kg CO₂ eq., reflecting Schneider Electric’s eco‑design philosophy.
