It is designed for AC distribution networks at 50/60 Hz and provides a 6 kA breaking capacity (Icn) at 400 V, certified to EN/IEC 60898-1. Clip-on mounting to a standard DIN rail (35 mm). The 54 mm width occupies 6 × 9 mm pitches on the rail, leaving room for adjacent modules in a crowded enclosure. Depth is 78.5 mm, height 85 mm — verify gland-plate clearance if the panel is shallow. Tunnel terminals accept 1–35 mm² rigid or 1–25 mm² flexible cable; strip length is 14 mm. IP20 rated for indoor panel use only. The 6 kA Icn at 400 V AC meets the requirement for most commercial and light-industrial sub-distribution boards. Rated insulation voltage is 440 V AC.","metaTitle":"A9K23340 Acti9 iK60N MCB, 3P, 40 A, Curve B, 6 kA","metaDescription":"Schneider Electric A9K23340 Acti9 iK60N miniature circuit breaker, 3-pole, 40 A, curve B, 6 kA breaking capacity at 400 V AC.
