The Schneider Electric A9F05363 is an Acti9 iC60N miniature circuit breaker rated for 63 A on a 3-pole configuration with a D tripping curve. It carries a 36 kA Icu breaking capacity at 12–133 V AC, stepping down to 10 kA Icu at 380–415 V AC per EN/IEC 60947-2, and 10 kA Icn at 400 V AC per EN/IEC 60898-1.
At 400 V AC, the A9F05363 delivers 10 kA Icn under EN/IEC 60898-1 and 10 kA Icu under EN/IEC 60947-2. That Icu figure is the same at 380–415 V AC, so the part holds its interrupting rating across the common European low-voltage distribution band. For a panel builder coordinating downstream MCBs with an upstream molded-case or air circuit breaker, that 10 kA at 400 V gives a solid selectivity window — the iC60N will clear a fault before the upstream device sees it, provided the upstream breaker's instantaneous trip is set above 10 kA.
The A9F05363 carries a current lifecycle status from Schneider Electric. It is an active catalog item within the Acti9 range, which means it remains a standard BOM line for new panel designs and replacement spares.
IP20 rated, so it lives inside an enclosure — no washdown exposure. The toggle actuator and trip indicator provide local visual status, and the contact position indicator confirms isolation suitability per both EN/IEC 60898-1 and 60947-2.
