The 3P+N configuration switches all three phases and provides a switched neutral on the left pole, per the neutral position spec. Breaking capacity is dual-rated: 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V, 10 kA at 380–415 V, and 6 kA at 440 V per EN/IEC 60947-2, plus 6 kA Icn at 400 V per EN/IEC 60898-1. The higher Icu figures under 240 V mean this breaker handles substantial fault current on low-voltage secondary side of a transformer or in a sub-distribution board. The dual standard certification (60947-2 for industrial and 60898-1 for residential/commercial) gives flexibility for BOM consolidation across different installation types. ## DIN Rail Integration and Panel Fit Mounts on standard DIN rail per the mounting support spec. Width is 72 mm (8 x 9 mm pitches), height 91 mm, depth 78.5 mm. The double terminal accepts 1–35 mm² rigid or 1–25 mm² flexible wire; strip length is 14 mm. IP20 rated, so it belongs inside a panel enclosure, not exposed to washdown. Suitability for isolation is confirmed under both standards. Overvoltage category IV — suitable for main distribution board installation.","metaTitle":"A9F03750 Acti9 iC60N MCB, 50 A, 3P+N, B Curve, 36 kA","metaDescription":"Schneider Electric A9F03750 Acti9 iC60N miniature circuit breaker, 50 A rated, 3P+N, B curve, 36 kA Icu at 133 V AC.
