For a 400 V distribution board, the Icn (service breaking capacity per EN/IEC 60898-1) is 10 kA — that is the rating for repeated clearing under normal service conditions. The C-curve means magnetic trip occurs at 5–10× In (40 A), so instantaneous trip is between 200 A and 400 A. That keeps the line moving: nuisance trips are rare on motor inrush or transformer energisation. Snaps onto standard DIN rail. Width is 72 mm (8 × 9 mm pitches), depth 78.5 mm, height 91 mm.","metaTitle":"Schneider Electric A9F07440 Acti9 iC60H MCB, 40 A, 4P, C-Cur","metaDescription":"Schneider Electric A9F07440 Acti9 iC60H miniature circuit breaker, 40 A rated, 4 poles, C-curve, 42 kA breaking capacity at 12-133 V AC.
