The A9F79116 is a 16‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N range, designed with a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve strikes a practical balance between overload protection and immunity to moderate inrush currents, making it a natural fit for general‑purpose distribution circuits – including lighting networks, receptacle outlets, small power tools, and control panels – across commercial buildings, light industrial sites, and residential complexes. This MCB is certified to both the industrial standard EN/IEC 60947‑2 and the residential standard EN/IEC 60898‑1, offering a versatile solution for projects that require cross‑standard acceptance. It delivers a dependable ultimate breaking capacity of 10 kA at 220‑240 V AC (per IEC 60947‑2) and 6 kA at 230 V AC (per IEC 60898‑1), ensuring robust fault interruption in diverse grid conditions. The device incorporates the well‑known VisiTrip indicator window, which visually flags the tripped pole to accelerate fault diagnosis, and the VisiSafe green strip that provides a visible and unambiguous confirmation of contact opening – an essential safety feature for any downstream maintenance activity. Its quick‑make/quick‑break mechanism, independent of the toggle position, guarantees consistent 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 tightening torque. The breaker offers IP20 protection at the terminals and IP40 when housed in an enclosure, operates from -35 °C to +70 °C, and is built with halogen‑free plastics and PVC‑free materials, achieving a 54% recyclability rate and a total lifecycle carbon footprint of 14 kg CO₂ eq.
