According to the ac contactor coil voltage of the control motor, the working voltage of the selected protector should be consistent with the ac contactor coil voltage.The working voltage of the motor protector is ac 380V or 220V (including the working voltage of the contact of the series of products without power input). Other working voltages need special customization.For example 1: the AC contactor coil voltage of a three-phase 380V AC motor control box is AC380V, the working voltage of the motor protector should be selected as AC380V.
For example 2: the AC contactor coil voltage of a three-phase 380V AC motor control box is AC220V, the working voltage of the motor protector should be AC220V.
For example 3: the coil voltage of ac contactor in the control box of a three-phase 660V ac motor is AC24V, and the working voltage of the motor protector should be AC24V. This product needs special customization.
