The Schneider Electric Acti9 iC60H A9F55301 is a versatile three-pole miniature circuit breaker engineered for low-voltage distribution networks. Rated at 1A with a D-curve thermal-magnetic trip unit, it effectively safeguards circuits against short circuits and overloads, particularly those with high inrush currents. It delivers exceptional breaking capacity, reaching up to 70 kA at 220–240 V AC under the industrial EN/IEC 60947-2 standard and 10,000 A at 415 V AC under the residential EN/IEC 60898-1 standard, while also supporting DC applications up to 180 V. Key features include the VisiTrip fault indicator, which pinpoints the faulted circuit to minimize downtime, and the VisiSafe green strip, which confirms physical contact opening for safe maintenance. A fast-closing mechanism, independent of manual operation, significantly extends the breaker's lifespan, supporting up to 10,000 electrical and 20,000 mechanical cycles. With a compact 54 mm width (six 9 mm pitches) and standard 35 mm DIN rail clip-on mounting, it ensures easy installation in space-constrained panels. The device operates reliably from -35 °C to +70 °C, offers IP20 terminal protection, and features a halogen-free, PVC-free construction with a 54% recyclability potential.
