Schneider Electric A9F74204 Miniature Circuit Breaker

Schneider Electric A9F74204 is an Acti9 iC60N miniature circuit breaker (MCB) designed for DIN-rail mounting in low-voltage distribution panels, configured as a 2-pole device with a rated current of 4 A and a C-curve thermal-magnetic trip for general-purpose protection across distribution circuits. It is rated for 400 V AC (typical 380–415 V systems in many regions) and provides interruption capacities of 6,000 A under IEC 60898-1 and up to 50 kA under IEC 60947-2, enabling safe disconnection of fault currents in common residential, commercial, and light-industrial installations. As part of Schneider Electric's Acti9 iC60N family, the A9F74204 complies with EN 60947-2/IEC 60947-2 and EN 60898-1/IEC 60898-1 standards, supporting reliable branch-circuit protection and protection of wiring and loads within distribution boards, control panels, and other enclosure-based electrical installations. This 2P 4A MCB is designed to operate within Schneider's Acti9 ecosystem and is compatible with the standard Acti9 DIN-rail mounting approach, providing consistent protection performance across devices used in commercial and industrial power distribution.
