It delivers 18.5 kW in AC-2 duty at 400 V, meaning it handles wound-rotor or slip-ring motor starting where the contactor opens under load — a heavier duty cycle than AC-3. At 500 V it's rated 22 kW, and at 690 V it drops to 11.4 kW, so the voltage derating matters if you're running a 690 V line.
Dimensions are 55 mm wide, 112 mm high, 115 mm deep.
Terminals and wiring
Main circuit terminals are screw-type, accepting 2x (0.75...25 mm²) stranded or 2x (0.25...2.5 mm²) solid. That's enough for the full rated current without piggyback lugs. Auxiliary contacts are rated at 24 V / 10 A, 60 V / 2 A, 110 V / 1 A, 220 V / 0.3 A, 230 V / 6 A, and 400 V / 3 A — check your control voltage against the curve; the 230 V rating at 6 A is the one most often used for PLC outputs driving the coil.
Coil and operating characteristics
Coil is rated for 50 Hz at 110 V and 60 Hz at 120 V. The operating range factor is 0.8 to 1.1 of rated voltage at both 50 and 60 Hz, so the coil holds in down to 88 V on a 110 V line and picks up reliably.
