The ABB AF190-30-11-11 is a 3-pole contactor rated for 156 A, with a coil voltage range of 20-60 V.
What the 156 A rating means for your application
The 156 A rating is the contactor's thermal current (Ith) for AC-1 duty — resistive loads like heaters. For motor starting (AC-3), the actual make/break current will be lower; verify the motor FLA against the contactor's AC-3 rating in the datasheet. The 20-60 V coil gives you flexibility across 24 VDC or 48 VAC control systems.
