The A9F55206 is a two‑pole (2P) miniature circuit breaker from Schneider Electric’s Acti9 iC60H family, rated at 6 A with a D‑curve tripping characteristic. The D‑curve, with its high magnetic threshold (12 × In), is specifically designed for circuits that experience significant inrush currents – think motor starters, transformers, solenoid valves, and capacitive loads – where B‑ or C‑curve breakers would trip unnecessarily. This 2‑pole device protects both poles simultaneously, making it ideal for single‑phase AC or DC applications requiring complete line isolation. It delivers a robust ultimate breaking capacity of 30 kA at 220‑240 V AC (per IEC 60947‑2) and 10 kA at 415 V AC (per IEC 60898‑1), ensuring reliable fault clearance across industrial and commercial installations. The breaker is dual‑certified to both industrial and residential standards, offering flexibility in mixed‑use environments. It features the intuitive VisiTrip indicator window, which instantly reveals the tripped pole to slash troubleshooting time, and the VisiSafe green strip that provides undeniable visual proof of contact separation – a critical safety feature for maintenance crews. 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 36 mm width (4 modular pitches) and DIN‑rail mounting, it optimises panel space, while the double‑tunnel terminals accept conductors up to 25 mm² (rigid) and 16 mm² (flexible). Operating reliably from -35 °C to +70 °C, this MCB is built with halogen‑free plastics and PVC‑free materials, achieving 54% recyclability and a total lifecycle carbon footprint of 16 kg CO₂ eq. – all reflecting Schneider Electric’s commitment to sustainable and safe energy distribution.
