**
Use with more than the number of passes shown above is possible.
Adjust the number of passes according to the rated current of the motor.
*** The rated current is the current at full load.
**** Supply: Low-voltage 3-phase basket type inductive motor, full-load characteristics of 200 VAC, 4-pole, totally-enclosed.
Note:
When using a large-capacity or high-voltage motor whose capacity is 45 kW or more, calculate the rated current/alternating current ratio by
converting with the alternating current ratio of the external current transformer.
