The ABB AF16-22-00-41 is a 4-pole contactor carrying an AC1 resistive-load rating of 30 A, with a 24 V coil. For motor duty (AC-3), expect a lower figure; the 30 A AC1 rating is the ceiling for non-inductive switching.
This is a DIN-rail-mount contactor, sized for standard 35 mm rail. The 4-pole layout handles three-phase plus neutral or two independent load circuits. Coil holds at 24 VDC nominal; verify the control transformer sizing if driving multiple contactors from one supply.
