The B-curve means the magnetic trip operates at 4 x In ±20 % — so between 19.2 A and 28.8 A — making it the standard choice for resistive or general-purpose loads where inrush is low. It is dual-rated to EN/IEC 60898-1 (for household/similar installations) and EN/IEC 60947-2 (for industrial applications), which gives it a 10 kA Icn at 415 V AC under the 60898 standard and a 36 kA Icu at 133 V AC under 60947-2. That 36 kA figure is the ultimate breaking capacity at the low-voltage end of its range — useful where fault current is high but the service voltage stays under 133 V AC. At 220–240 V AC the Icu drops to 20 kA, and at 380–415 V AC to 10 kA, so selectivity studies should use the voltage-specific rating, not the headline number. The 4-pole body takes 8 x 9 mm pitches of rail space — 72 mm wide, 85 mm tall, 78.5 mm deep. IP20 finger-safe terminals accept 1–25 mm² rigid or 1–16 mm² flexible wire; strip length 14 mm, tighten to 2 N·m. The toggle actuator and trip indicator give local status without opening the door. Padlockable for lockout/tagout.","metaTitle":"Schneider Electric A9F43406 Acti9 iC60N MCB, B-Curve 6A 4P,","metaDescription":"Schneider Electric A9F43406 Acti9 iC60N miniature circuit breaker, 6A B-curve 4P, 36kA Icu at 133V AC.
