The A9F79125 is a 25‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, featuring a C‑curve tripping characteristic (magnetic trip set at 8 × In). The C‑curve provides a well‑balanced response between thermal overload protection and tolerance of moderate inrush currents, making this device an ideal solution for general‑purpose distribution circuits – including lighting networks, socket outlets, control panels, and small motor feeders – across commercial, industrial, and residential environments. This MCB delivers a reliable ultimate breaking capacity of 10 kA at 220‑240 V AC under the EN/IEC 60947‑2 industrial standard, and 6 kA at 230 V AC per the EN/IEC 60898‑1 residential norm, ensuring robust fault protection in diverse installations. The breaker integrates the well‑known VisiTrip window, which visually flags the tripped pole to accelerate fault diagnosis, alongside the VisiSafe green strip that provides undeniable proof of contact separation – a critical safety feature for maintenance personnel. Its quick‑make/quick‑break mechanism, independent of handle 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 maximises panel space. The double‑tunnel terminals accept rigid conductors up to 25 mm² and flexible up to 16 mm², with a tightening torque of 2 N·m. The device offers IP20 protection at the terminals and IP40 when enclosed in a modular cabinet, operating reliably from -35 °C to +70 °C. Sustainability features include halogen‑free plastics, PVC‑free construction, and a 54% recyclability rate, with a total lifecycle carbon footprint of 17 kg CO₂ eq. – transparently disclosed in the product’s environmental profile.
