The A9F75125 is a 25‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N range, featuring a D‑curve tripping characteristic (magnetic trip set at 12 × In). The D‑curve is purpose‑built for circuits that draw high inrush currents – such as motor starters, transformers, solenoid valves, and capacitive loads – where lower‑curve devices (B or C) would be prone to nuisance tripping. This MCB delivers a proven ultimate breaking capacity of 10 kA at 220‑240 V AC under the industrial standard EN/IEC 60947‑2 (with higher values at reduced voltages) and 6 kA at 230 V AC per the residential norm EN/IEC 60898‑1, ensuring reliable fault interruption across a broad spectrum of applications. It is dual‑certified to both standards, offering flexible integration into industrial control panels, commercial distribution boards, and heavy‑duty residential installations. Designed with Class‑2 insulation for enhanced operator safety, the breaker also coordinates seamlessly with Acti 9 RCDs and Compact NSX MCCBs, simplifying system design. The device incorporates the intuitive VisiTrip fault‑finder window, which instantly highlights the tripped pole to accelerate troubleshooting, and the VisiSafe green strip that delivers unmistakable visual confirmation of contact opening – a critical safety feature for maintenance crews. Its quick‑make/quick‑break mechanism, independent of toggle position, guarantees 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 saves 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 tightening 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 and PVC‑free materials, achieving a 54% recyclability rate and a total lifecycle carbon footprint of 17 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, energy‑efficient solutions.
