Product selection & Size
The 2.3KV voltage level can be replaced with the product of 3.3kv voltage grade; 4.16kv and 6.6kv voltage grade can use 6kv voltage gradeProduct replacement. The soft stater must be selected based on the rated current on the motor nameplate (even if the motor is not running atfull load). table The corresponding KW value given in the above is for reference only. But pay attenion to diferent vollage levels when themotor power is the same when the curent is diferent, select type No. Please calculate the curent according to the power before confirming
