What the 9 A AC-3 rating means for fit
The AF09-30-01-14: The 9 A AC-3 rating governs motor switching — it handles the inrush and break current of a small induction motor, typically up to about 3 kW at 400 V three-phase. For resistive or heating loads (AC-1), the contactor can carry a higher current, but the AC-3 figure is the one that decides motor fit. If your BOM line calls for a 9 A AC-3 contactor, this is the rating that confirms the match.
