The key rating for motor duty is 23 kW at 400 V, 60 °C under AC-3e switching category — that's the figure that governs real motor starting and stopping on a 400 V line. At 690 V the same duty delivers 40 kW, and at 230 V it's 13.3 kW. Side-by-side mounting is allowed without derating.
Integration notes
At 45 mm wide and 97 mm deep, the S0 frame fits standard DIN-rail enclosures. The screw terminals accept 2x (0.5 to 1.5 mm²) solid or stranded for control wiring, and 2x (16 to 12 AWG) for the main contacts. Maximum switching frequency at AC-3 is 1,000 cycles per hour, dropping to 300 cycles per hour at AC-4 for plugging or inching duty. The coil draws 6 A at 24 V rated value, 1 A at 110 V, and 0.3 A at 220 V.
