According to the AC contactor coil voltage of the control motor, the selection of the working voltage of the protector should be consistent with the AC contactor coil voltage. The working voltage of conventional motor protector products (including contacts working voltage of series products without power input) is 380V or 220V. Other working voltage needs special customization.
1: The AC contactor coil voltage of a three-phase 380V AC motor control box is AC 380V, and the working voltage of the motor protector should be AC 380V.
2: The AC contactor coil voltage of a three-phase 380V AC motor control box is AC 220V, and the working voltage of the motor protector should be AC 220V.
3: The AC contactor coil voltage of a three-phase 660V AC motor control box is AC24V, and the working voltage of the motor protector should be AC24V, which needs special customization.
