The 36 kA Icu at low voltage (12–133 V AC) gives serious fault-current headroom; at 380–415 V AC it still interrupts 10 kA Icu, and the IEC 60898-1 Icn is 6000 A at 400 V AC. That dual-rating (60947-2 for industrial, 60898-1 for domestic/commercial) means it's accepted in both worlds — a panel builder can spec it for a factory distribution board or a commercial riser. That's 8 modules of 9 mm pitch, so it fills eight positions on the rail. Double terminals top and bottom accept up to 35 mm² rigid or 25 mm² flexible; strip 14 mm and torque to 3.5 N.m. IP20 finger-safe front, pollution degree 3 — fine for a clean panel, but keep it behind a gland plate if the enclosure sees dust or moisture.","metaTitle":"Schneider Electric A9F04740 Acti9 iC60N MCB, 40 A, 3P+N, C-C","metaDescription":"Schneider Electric A9F04740 Acti9 iC60N miniature circuit-breaker, 40 A, 3P+N, C-curve, 36 kA breaking capacity.
