The A9F76306 is a three‑pole (3P) miniature circuit breaker from Schneider Electric’s Acti9 iC60N series, rated at 6 A with a B‑curve tripping characteristic (magnetic threshold at 4 × In). As a 3‑pole device protecting all three phases simultaneously, it is ideally suited for three‑phase AC systems where complete isolation of all lines is required – making it a reliable component for industrial control panels, motor control centres, lighting distribution boards, and commercial power networks. The B‑curve is specifically engineered for circuits with minimal or negligible inrush currents, such as resistive heating loads, lighting banks, and general‑purpose distribution, delivering precise overload and short‑circuit protection without nuisance tripping. This MCB provides a robust ultimate breaking capacity of 20 kA at 220‑240 V AC (per IEC 60947‑2) and 6 kA at 400 V AC (per IEC 60898‑1), ensuring dependable fault clearing in demanding three‑phase installations. It is dual‑certified to both industrial and residential standards, offering flexibility across project types. The breaker features the intuitive VisiTrip indicator, which instantly identifies the tripped pole for fast fault diagnosis, and the VisiSafe green strip that provides clear visual proof of contact opening – a critical safety feature for maintenance work. Its quick‑make/quick‑break mechanism, independent of handle position, ensures consistent performance over 10,000 electrical and 20,000 mechanical cycles. With a compact 54 mm width (6 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) with a 2 N·m torque. Operating reliably from -35 °C to +70 °C, this MCB is built with halogen‑free plastics and is RoHS compliant by exemption, achieving 54% recyclability.
