Rated insulation voltage is 440 V AC, and overvoltage category III applies — this breaker is designed for fixed installation inside a distribution panel, not for outdoor or portable use. IP20 protection means it is touch-safe but not washdown-rated. Thermal-magnetic trip technology gives you both thermal overload protection (bimetal strip) and magnetic short-circuit protection (solenoid). No earth-leakage protection built in — that would require a separate RCCB or RCBO upstream. Width is 72 mm (8 x 9 mm pitches), depth 78.5 mm, height 85 mm. Tunnel-type terminals accept 1 to 35 mm² rigid or 1 to 25 mm² flexible cable; tighten to 3.5 N·m. Wire strip length 14 mm.","metaTitle":"Schneider Electric A9K24740 Acti9 iK60N MCB, 40A C-curve 3P+","metaDescription":"Schneider Electric A9K24740 Acti9 iK60N miniature circuit-breaker, 40 A C-curve, 3P+N, 6 kA breaking capacity at 400 V AC, EN/IEC 60898-1.
