The Schneider Electric A9F07363 is an Acti9 iC60H miniature circuit breaker rated at 63 A with a C-curve trip characteristic and 3 protected poles.
Breaking capacity — what 15 kA at 400 V means for selectivity
This breaker carries a 15 kA Icu at 380...415 V AC and a 10 kA Icu at 440 V AC per EN/IEC 60947-2, plus a 10 kA Icn at 400 V AC per EN/IEC 60898-1. The dual certification (60947-2 for industrial and 60898-1 for household/commercial) gives flexibility to use it in either context, though the 60898-1 rating is the lower of the two at 10 kA.
DIN rail integration and wiring
IP20 finger-safe terminals are standard for enclosed panels; no washdown rating here, so keep it behind a gland plate. The toggle actuator and trip indicator give local visual status without opening the panel door.
Overvoltage category IV means it's rated for installation at the origin of the installation (utility side of the main panel).
