ABB UFC765AE102 3BHE003604R0102选择和应用建议：

1） 将接触器连接到星形，而不是Δ。推荐表基于星形连接。

2） 所有接触器都被认为是最终短路转子接触器。这补偿了由于主晶闸管控制引起的短时间低磁化和谐波对触点的额外加热。

3） 接触器的闭合操作是利用转子电流进行的。

典型值：转子额定电流的1,0-1,5倍。

4） 接触器的断开操作是在零转子电流的情况下进行的。

5） 安装温度为55摄氏度。将低于70摄氏度的值降低。

ABB UFC765AE102 3BHE003604R0102 Selection and Application Recommendations:

1) Connect the contactor to the star, not the Delta. Recommendation tables are based on star connections.

2) All contactors are considered to be final short-circuited rotor contactors. This compensates for short periods of low magnetization and additional heating of the contacts by harmonics due to the main thyristor control.

3) The closing operation of the contactor is carried out using the rotor current.

Typical value: 1,0-1,5 times the rated rotor current.

4) The disconnection operation of the contactor is carried out under the condition of zero rotor current.

5) The installation temperature is 55 degrees Celsius. Lower the value below 70 degrees Celsius.
