This breaker carries dual-standard ratings: 20 kA Icu at 240 V AC per EN/IEC 60947-2, and 10 kA Icn at 400 V AC per EN/IEC 60898-1. The 6 kA Icu at 440 V AC covers the higher-voltage corner. Limitation class 3 means it restricts let-through energy enough to protect downstream equipment in most fault conditions. ## Panel integration The 36 mm width (2-pole) occupies four 9 mm module positions — plan your enclosure fill accordingly. The toggle actuator provides local on/off and a trip-indicator flag for quick visual identification of a tripped circuit.","metaTitle":"Schneider Electric A9F05263 Acti9 iC60N MCB, D Curve, 63 A,","metaDescription":"Schneider Electric A9F05263 Acti9 iC60N miniature circuit breaker, 63 A, D curve, 2-pole, 36 mm wide, 20 kA at 240 V AC.
