Product details

Rated at 18.5 kW at 400 V in AC-2 duty (slip-ring motor starting) and 35 A in AC-4 duty (plugging/reversing), this contactor handles the heavy switching cycles those applications demand. The AC-1 resistive rating supports 1,200 operations per hour, while AC-4 maxes at 300 per hour — the thermal limits for inching and reversing. The coil draws 24 V at 50 Hz, with a pickup range of 0.8 to 1.1 times rated voltage.

Screw-type terminals on the main circuit accept solid conductors 2x (0.25 to 2.5 mm²) and stranded 2x (0.75 to 25 mm²). The auxiliary circuit uses 2x (0.75 to 16 mm²) stranded.
