The A9F08163 is a 1-pole Acti9 iC60H miniature circuit-breaker rated 63 A with a D tripping curve. The 42 kA Icu at 12-60 V AC (per EN/IEC 60947-2) tells you it can safely interrupt a fault up to that level without upstream cascading; at 230 V AC the Icn is 10 kA per EN/IEC 60898-1, which is the domestic/light-commercial standard.
Mounts on DIN rail (EN 60715). The toggle and trip indicator are visible through the panel door.
Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic). Pollution degree 3, overvoltage category IV. Suitability for isolation is confirmed under both standards. No earth-leakage protection built in — that is handled separately by a residual-current device upstream.
