The A9F77106 is a 6‑ampere, single‑pole miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, engineered with a C‑curve tripping characteristic (magnetic threshold at 8 × In). The C‑curve provides a well‑balanced response between overload protection and tolerance of moderate inrush currents, making it a versatile choice for general‑purpose distribution – including lighting circuits, socket outlets, small power feeders, and control panels in commercial, industrial, and residential installations. This MCB delivers a rated ultimate breaking capacity of 10 kA at 220‑240 V AC under the industrial EN/IEC 60947‑2 standard (with higher ratings at lower voltages) and 6 kA at 230 V AC per the residential EN/IEC 60898‑1 norm, ensuring reliable fault interruption across a wide spectrum of applications. Certified to both standards, it offers seamless integration into mixed‑use projects. Designed with Class‑2 insulation for enhanced operator safety, the breaker also coordinates fully 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 shorten troubleshooting time, and the VisiSafe green strip that delivers clear visual confirmation of contact opening – a critical safety feature for maintenance personnel. 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 only 8 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable, energy‑efficient solutions.
