* The squares (@) represent the symbols defined under Model Number Legend.
** 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.
