The 50 kA Icu at 400 V AC (EN/IEC 60947-2) means it can safely interrupt a fault up to 50,000 A without welding or bursting — that is high fault-current headroom for industrial panelboards fed by large transformers. The 10 kA Icn at 400 V (EN/IEC 60898-1) is the domestic/light-commercial rating; the 50 kA Icu is what matters for industrial coordination. Snaps onto standard DIN rail (mounting support: DIN rail). Occupies 8 x 9 mm pitches (72 mm wide). Depth is 78.5 mm, height 91 mm — fits standard distribution boards. Terminals accept 1–25 mm² rigid or 1–16 mm² flexible wire; tightening torque 2 N.m. Strip length 14 mm. IP20 finger-safe. Overvoltage category IV (mains entry). Suitable for isolation per both standards — the contact position indicator and trip indicator confirm open contacts visually.","metaTitle":"A9F05402 Acti9 iC60N MCB, 2 A, Curve D, 4P, 50 kA","metaDescription":"Schneider Electric A9F05402 Acti9 iC60N miniature circuit breaker, 2 A rated, curve D, 4 poles, 50 kA Icu breaking capacity at 400 V.
