The ABB AF75-40-00-70 is a 4-pole contactor from the AF75 series, with a control coil rated for 110-250 V at 50/60 Hz. It's an active, current-production part, so you're not chasing NOS or surplus for a BOM line that needs to stay fed.
Four poles on a contactor this size typically means you've got three for motor switching and one spare for a resistive load or an auxiliary interlock. The 110-250 V coil covers most common control voltages across 50 and 60 Hz plants — you don't need a separate transformer tap for a 208 V or 240 V control bus.
