Notes

  1. Max. power consumption values are for 50 Hz operation. Multiply these values by a factor of 1.2 for 60 Hz operation. The max. operating current remains the same.
    Max. operating current / max. power consumption when selecting contactors, leads and fuses. Contactors: Category AC3.
  2. Tolerance (± 10%) based on the mean voltage range. Other voltages and current types on request
    380-420 V Δ/ YYY - 3 - 50 Hz PW
    440-480 V Δ/ YYY - 3 - 60 Hz PW
    PW = Part Winding, motors for part winding start
    (unloaded start not required) Wind ratio: 60% / 40%
