Electrical Ratings: 890SD Frame B, 380-500V
Input currents are listed at 400Vac and 50Hz or 460Vac and 60Hz. Suitable for use in a circuit capable of delivering not more
than 10000 rms Symmetrical Amperes. Motor power, input current and output current must not be exceeded under steady
state operating conditions.

Notes:
1) Based on a 10ms rectangular current pulse. 2) Based on 30% duty at a braking resistor appropriate for braking at 100% of drive rated power.
3) Up to the highest supply voltage that maintains shaft power less than the product power rating, for a typical induction motor. Derated for operation above this supply voltage.
4) Products take less input current when operated in these modes, than stated. 5) Based on a permanent-magnet motor with efficiency 90% and power factor 0.9.
