The ABB AF146-30-22-13 is a 3-pole contactor rated at 130 A, from the AF contactor series. The 130 A rating is the conventional free-air thermal current (Ith) — the continuous current the main poles can carry in open air at 40 °C ambient. For motor switching, you derate to the AC-3 duty current, which for this frame size typically lands around 110–115 A; that's the figure to use when sizing for a motor load like a pump or conveyor.
Deployment context
The 130 A rating means it's sized for a 55–75 kW motor at 400 V three-phase, typical for a medium conveyor drive or a large pump. The AF series uses an electronic coil interface that holds in at low DC power — so the control transformer can be smaller than with an AC coil of the same rating.
