典型应用包括电动机控制、负载检测及管理、电源和过流保护。

Typical applications include motor control, load detection and management, power supplies, and overcurrent fault protection.

电动机的负载电流不得超过额定值，三相电流平衡。

The electric motor should not overload, three -phase current should be balance.

因此，电动机的“热”在最大负荷，和“酷”在无负载。

Thus the motor is "hot" at Max load, and "cool" at no load.
