Overview
The A9F86463 is a Schneider Acti9 iC60H miniature circuit breaker rated 63 A switching current on a B curve, with 4 poles and a 42 kA breaking capacity (Icu) under IEC 60947-2. It carries dual-standard certification to both IEC 60947-2 and IEC 60898-1, covering industrial distribution and residential-grade branch circuits. The thermal-magnetic trip unit triggers magnetically at 4 x In (±20%), and the housing is rated IP20 with a pollution degree of 3 per IEC 60947-2.
Compared to the A9F89463, which carries a C curve and 50 A switching current, the A9F86463 offers a higher 63 A rating and a B curve (4 x In magnetic trip vs 8 x In). Choose the A9F86463 when the load inrush is low and the design needs the full 63 A continuous capacity; pick the A9F89463 when the branch circuit requires a C curve for moderate motor or transformer inrush.
