It is rated for 45 kW at 500 V in AC-3 duty, which means it handles the inrush and run currents of a standard squirrel-cage motor up to that power level.
If your application cycles the motor in reverse or jogs frequently, this is the rating that governs contactor life, not the AC-3 figure. The AC-3 maximum switching rate is 1 000 operations per hour, while AC-4 drops to 300 per hour — a real constraint for high-cycle reversing conveyors or hoists. The contactor accepts screw-type terminals on the main circuit, with solid wire up to 2x 2.5 mm² and stranded up to 2x 50 mm². That stranded capacity is generous for a size S3 — it can take a 50 mm² cable on each pole, which is unusual for this frame size and simplifies paralleling for high-current feeds.
Dimensions are 146 mm high, 100 mm wide, 139 mm deep — fits a standard S3 footprint. Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail without derating for thermal stack-up, as long as the ambient stays within the -25 to +60 °C range.
