Integrator's quick-fit note
It's rated for motor switching at 7.5 kW on a 500 V or 690 V line, and handles AC-4 duty (plugging/reversing/inching) at 12.5 A. The coil is 24 VDC, pulling 10 A inrush at that voltage.
The 7.5 kW rating at 500 V and 690 V tells you this contactor is sized for a 10 HP motor on a 480 V system (common North American voltage) or a standard 7.5 kW IEC motor on a 690 V mining/industrial supply. The AC-4 current of 12.5 A is the limiting factor for reversing or jogging applications — that's the current the contacts can interrupt during inching duty without excessive wear. For straight AC-3 starting, the contactor will handle higher currents, but the evidence doesn't list that specific value. The 3-pole NO configuration means it switches all three phases; there's no built-in auxiliary contact, so you'll need a separate 3RT19 block if you want a feedback signal to the PLC.
Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) for the smaller range; the power terminals handle 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), or max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), or 1x 8. The coil terminals are separate and rated for 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V.
