It delivers 6 kA breaking capacity (Icn) at 400 V AC 50/60 Hz per EN/IEC 60898-1 — enough for most final-distribution branch circuits in residential or light commercial panels where the prospective fault current stays under that threshold. The thermal-magnetic trip unit covers overload and short-circuit protection for two protected poles. Depth is 78.5 mm, height 85 mm, so it clears most shallow consumer units and distribution boards. Tunnel-type terminals accept 1...25 mm² rigid or 1...16 mm² flexible on top or bottom; wire strip length 14 mm, tightening torque 2 N·m. IP20 finger-safe protection for the front face once installed.","metaTitle":"Schneider Electric A9K23203 Acti9 iK60N MCB, 3 A, B Curve, 2","metaDescription":"Schneider Electric A9K23203 Acti9 iK60N miniature circuit breaker, 3 A rated current, B curve, 2 poles, 6 kA breaking capacity at 400 V AC.
