Rated breaking capacity reaches 42 kA Icu at 12-133 V AC (EN/IEC 60947-2), stepping down to 30 kA at 220-240 V AC, 15 kA at 380-415 V AC, and 10 kA at 440 V AC. Under EN/IEC 60898-1 it is rated 15 kA Icn at 400 V AC. That dual-standard rating means this breaker can serve both industrial (60947-2) and residential/commercial (60898-1) installations, but the 60947-2 figures govern for industrial panel builds where fault current may exceed 10 kA. The B curve trips magnetically at 4 x In (±20 %), so for a 40 A breaker the magnetic release engages between 128 A and 192 A. This suits cable protection in circuits with low inrush — lighting, resistive loads, or long distribution runs where you want fast clearing on short-circuit but tolerance for moderate startup peaks. Snap-on DIN rail mounting, 54 mm wide (6 x 9 mm pitches). The 78.5 mm depth and 91 mm height fit standard distribution board cutouts. Overvoltage category IV covers the main distribution board entry point. IP20 finger-safe terminals. Earth-leakage protection requires a separate block (Vigi iC60) — the MCB itself does not include RCD functionality.","metaTitle":"Schneider Electric A9F06340 Acti9 iC60H MCB, 40 A, 3P, B Cur","metaDescription":"Schneider Electric A9F06340 Acti9 iC60H miniature circuit breaker, 40 A, 3-pole, B curve, 42 kA breaking capacity at 12-133 V AC.
