The A9F54125 is a 25‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60H series, featuring a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve provides an optimal balance between thermal overload protection and tolerance of moderate inrush currents, making it a go‑to choice for general‑purpose distribution circuits – including lighting banks, power outlets, small motor feeders, and control panels – across commercial, industrial, and residential installations. This MCB delivers a dependable ultimate breaking capacity of 15 kA at 220‑240 V AC under the industrial EN/IEC 60947‑2 standard, and 10 kA at 240 V AC per the residential EN/IEC 60898‑1 norm, ensuring reliable fault clearance in diverse grid conditions. It is certified to both standards, providing flexibility for mixed‑use projects. The device incorporates Schneider’s proven VisiTrip indicator window, which instantly highlights the tripped pole to reduce diagnostic downtime, and the VisiSafe green strip that provides clear visual evidence of contact separation – an essential safety check for any downstream maintenance activity. Its quick‑make/quick‑break mechanism, independent of 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 both rigid and flexible conductors up to 25 mm², with a 2 N·m tightening torque. The breaker offers IP20 terminal protection, operates reliably from -35 °C to +70 °C, and is built with halogen‑free plastics and PVC‑free materials, achieving a 54% recyclability rate. Its total lifecycle carbon footprint is quantified at 17 kg CO₂ eq., reflecting Schneider Electric’s commitment to sustainable energy management.
