The A9F54116 is a 16‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H family, equipped with a C‑curve tripping characteristic (magnetic trip set at 8 × In). The C‑curve provides an optimal trade‑off between overload protection and tolerance of moderate inrush currents, making it a preferred solution for general lighting, power sockets, small motors, and control circuits in commercial, industrial, and residential installations. This MCB is built to dual‑standard compliance – meeting both the industrial EN/IEC 60947‑2 and the residential EN/IEC 60898‑1 norms – which ensures its seamless integration into diverse projects, from factory automation panels to consumer distribution boards. Engineered with Class‑2 insulation, it guarantees continuous operator safety even for unqualified personnel, and its full coordination with Acti 9 RCDs and Compact NSX MCCBs simplifies system design. The breaker features the practical VisiTrip window, which visually pinpoints the tripped pole to slash troubleshooting time, and the VisiSafe green strip that delivers undeniable proof of contact separation – an indispensable safety check before any downstream maintenance. Its fast‑make/quick‑break mechanism, independent of handle position, assures consistent switching performance over 10,000 electrical and 20,000 mechanical cycles. Despite its 16 A rating, the device retains a compact 18 mm width (2 modular pitches) and clips onto DIN rails, saving 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, and the breaker operates reliably from -35 °C to +70 °C. Sustainability is addressed with halogen‑free plastics, PVC‑free construction, silicone‑free materials, and a 54% recyclability rate, all contributing to a total lifecycle carbon footprint of 14 kg CO₂ eq., backed by Schneider Electric’s transparent environmental disclosure.
