The Schneider Electric A9F07463 is an Acti9 iC60H miniature circuit breaker rated 63 A with a C-curve trip characteristic, 4 protected poles, and a 42 kA ultimate breaking capacity (Icu) at 12–133 V AC.
The 63 A C-curve means the magnetic trip activates at 8 x In ±20 % — roughly 504 A instantaneous — which suits moderate inrush loads like lighting banks, small motor groups, or transformer primaries without nuisance tripping. The 42 kA Icu at low voltage drops to 30 kA at 220–240 V and 15 kA at 380–415 V; that 15 kA at 400 V is the figure to coordinate with downstream branch breakers in a typical European distribution board. Overvoltage category IV and pollution degree 3 mean this breaker is rated for the main incoming supply at the service entrance — not just sub-distribution — in environments with conductive dust or humidity.
