The A9F74116 is a 16‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, featuring a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve provides an ideal balance between overload protection and tolerance of moderate inrush currents, making it a versatile solution for general‑purpose distribution – including lighting circuits, socket outlets, small power feeders, and control panels in commercial, industrial, and residential installations. This MCB delivers a rated ultimate 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 per the residential EN/IEC 60898‑1 norm, ensuring reliable fault interruption across a broad spectrum of applications. It is certified to both standards, allowing seamless integration into mixed‑use projects. 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 design. The device incorporates the field‑proven VisiTrip fault‑finder window, which instantly highlights the tripped pole to reduce downtime, and the VisiSafe green strip that delivers undeniable visual confirmation of contact separation – a critical safety feature for maintenance personnel. Its quick‑make/quick‑break mechanism, independent of handle position, ensures 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 optimises 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 reliably from -35 °C to +70 °C, and is built with halogen‑free plastics, PVC‑free materials, and silicone‑free construction, achieving a 54% recyclability rate and a total lifecycle carbon footprint of 14 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable energy management.
