The ABB AF190-30-22-13 is a 3-pole contactor rated for 156 A, with a 100-250 VAC/DC coil. It's part of ABB's AF contactor family, which uses an electronic coil interface to handle wide voltage swings without a separate control transformer — useful when the control voltage is unstable or you're standardizing across multiple panel voltages. The 156 A rating places it in the heavy motor-switching range for pumps, compressors, and conveyor drives on 400 V three-phase systems.
What the 156 A rating means for your load
The 156 A figure is the conventional free-air thermal current (Ith) for the contactor — the current it can carry continuously in open air at 40 °C ambient. For motor duty (AC-3), the actual switching current will be lower, typically around 150 A for a 75 kW 400 V motor. If you're replacing an existing contactor that was sized for a specific motor FLA, verify the AC-3 rating in the full datasheet; the 156 A Ith is the ceiling, not the motor-rated number.
