Schneider Electric iC65N 2-pole miniature circuit breaker for 400 V AC systems, model A9F18240, delivers a 40 A nominal rating with a C-curve trip characteristic and a 6 kA short‑circuit breaking capacity in a 4-module‑width enclosure. Part of the Acti9 iC65N family, this 2P device is available in ratings from 1 A through 40 A for 400 V networks—including common values 1 A, 2 A, 10 A, 16 A, 25 A and 32 A. As a two‑pole device, it interrupts both live conductors in 400 V circuits, making it suitable for protecting branch circuits in distribution panels and industrial installations.
