The A9F73101 is a 1‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, equipped with a B‑curve tripping characteristic (magnetic trip at 4 × In). The B‑curve is specifically designed for circuits with minimal inrush currents – such as lighting, resistive loads, and small control circuits – where precise overload protection is paramount without nuisance tripping. Despite its low current rating, this MCB delivers an exceptional ultimate breaking capacity of 50 kA at 220‑240 V AC under the industrial EN/IEC 60947‑2 standard, and 6 kA at 230 V AC per the residential EN/IEC 60898‑1 norm, ensuring reliable fault clearance in high‑fault‑current scenarios. It complies with both standards, making it suitable for mixed‑use installations from industrial panels to domestic consumer units. The breaker integrates the intuitive VisiTrip window, which instantly identifies the tripped pole to slash troubleshooting time, and the VisiSafe green strip that provides indisputable visual proof of contact separation – a vital safety feature for maintenance personnel. Its fast‑make/quick‑break mechanism, independent of the toggle handle, guarantees consistent performance over 10,000 electrical and 20,000 mechanical cycles. With a compact 18 mm width (2 modules) 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. The device offers IP20 terminal protection and IP40 when enclosed, operates from -35 °C to +70 °C, and is built with halogen‑free plastics, PVC‑free construction, and a 54% recyclability rate. Its total lifecycle carbon footprint is quantified at 14 kg CO₂ eq., all transparently disclosed in the product’s environmental profile.
