The C curve (magnetic tripping limit of 8 x In +/- 20%) means it's sized for moderate inrush loads — think general distribution circuits feeding socket outlets or small motor groups, not high-starting-current motor feeders where a D curve would be needed. The 10 kA Icn at 400 V AC conforming to EN/IEC 60898-1 tells you the breaking capacity under the domestic/light commercial standard; the 36 kA Icu at 12-133 V AC per EN/IEC 60947-2 covers the industrial fault rating at lower voltages. For a panel OEM wiring up a 4P distribution board, that 72 mm width (8 x 9 mm pitches) slots into a standard DIN-rail assembly with removable comb busbars — no special adaptors. ## Standards and deployment context The IP20B finger-safe terminals accept up to 25 mm² rigid or 16 mm² flexible, with a 2 N.m tightening torque and 14 mm strip length. Tropicalisation class 2 (95% RH per EN/IEC 60068-2-78) keeps the internal mechanism from corroding in high-humidity plant rooms.","metaTitle":"Schneider Electric A9F68420 Acti9 iT60 MCB, 20 A, 4P, C Curv","metaDescription":"Schneider Electric A9F68420 Acti9 iT60 miniature circuit breaker, 20 A rated current, 4 poles, C curve, 10 kA Icn at 400 V AC.
