At 220…240 V AC the breaking capacity is 20 kA, and at 380…415 V AC it drops to 10 kA; the 6 kA rating at 440 V AC covers the upper end. The thermal-magnetic trip unit with C curve (magnetic threshold 8 x In ±20 %) is sized for general-purpose distribution loads — lighting, small motor circuits, control transformers — where inrush isn't extreme but a standard B curve would nuisance-trip. The removable comb busbar is already installed, which speeds up panel wiring when ganging multiple breakers. Terminals accept 1…35 mm² rigid or 1…25 mm² flexible; wire stripping length is 14 mm, and tightening torque is 3.5 N.m.","metaTitle":"Schneider Electric A9F68440 Acti9 iT60 MCB, 40 A C Curve 4P,","metaDescription":"Schneider Electric A9F68440 Acti9 iT60 miniature circuit-breaker, 40 A, C curve, 4 poles, 36 kA breaking capacity at 133 V AC.
