Its 24 VDC coil pulls in reliably; the rated operating current at AC-3 duty reaches 30 kW at 500 V, which covers a standard 37 kW 4-pole induction motor on a 400 V line.
At 690 V the same duty drops to 11.4 kW, so if your line runs 690 V you need to check the motor nameplate against that lower ceiling. For resistive loads (AC-1) the mechanical life of 10 million operations is the limiting factor, not the electrical endurance. If your control transformer is marginal on regulation, factor in the 20 to 25 ms closing time and 10 to 15 ms arcing time when coordinating with upstream fuses or a motor-protective breaker.
Solid wire from 0.25 to 2.5 mm² and stranded from 0.75 to 25 mm² — that covers most motor feeder cables up to 6 mm² for a 30 kW load. Side-by-side mounting is allowed, which saves rail space in a multi-contactor group, but remember the thermal derating if you pack them tight at the upper end of the operating range (-25 to +60 °C,).
