The Schneider Electric A9F06463 is a 63 A, 4-pole miniature circuit breaker from the Acti9 iC60H series, with a B-curve trip characteristic. Rated at 63 A, this MCB handles the full load current of a submain or a large branch circuit.
The breaking capacity is 42 kA Icu at 12–133 V AC, 30 kA at 220–240 V AC, and 15 kA at 380–415 V AC (per EN/IEC 60947-2). At 400 V AC, the Icn is 15 kA per EN/IEC 60898-1. This dual-rated MCB meets both the industrial (60947-2) and domestic/light commercial (60898-1) standards, so it can be specified in a panel that requires industrial coordination or a residential load center.
Integration notes
Depth is 78.5 mm, height 91 mm. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible conductors; tightening torque is 3.5 N.m.
