What are the principles of selection of contactors?
When controlling the motor, the rated current of the main contact should be greater or slightly larger than the rated current of the motor
When the rated current of the contactor main contact is selected, the rated current of the main contact shall be equal to the rated current of the load
Select the rated voltage of the main contact of the contactor The rated voltage of the main contact of the contactor shall be greater than or equal to the rated voltage of the control circuit.
