The A9F55106 is a 6‑A, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, distinguished by its D‑curve tripping characteristic (magnetic threshold at 12 × In). This makes it the ideal choice for protecting circuits with high inrush currents – such as motor starters, transformers, solenoid valves, and capacitive loads – where B‑ or C‑curve devices would nuisance‑trip. Like its curve‑B siblings, this MCB offers dual‑standard compliance (EN/IEC 60947‑2 for industrial use and EN/IEC 60898‑1 for residential installations), giving specifiers flexibility across project types. The breaker is equipped with the VisiTrip fault‑indication window, which instantly reveals the tripped pole to slash troubleshooting time, and the VisiSafe green strip that provides a visible proof of contact separation – an essential safety feature for lockout/tagout procedures. Its fast‑make/quick‑break mechanism, independent of the toggle handle, ensures reliable operation over 10,000 electrical and 20,000 mechanical cycles. The compact 18 mm width (2 modules) and DIN‑rail clip mounting maximize panel density, while the double‑tunnel terminals accept rigid conductors up to 25 mm². Built for harsh environments, it operates from -35 °C to +70 °C and carries an IP20 rating for terminal protection. Sustainability is addressed with halogen‑free plastic parts, PVC‑free construction, and a 54% recyclability rate, with a total lifecycle carbon footprint of 8 kg CO₂ eq. – underscoring Schneider Electric’s commitment to eco‑efficient energy distribution.
