The main function of the electric forklift contactor is to close, carry and disconnect the normal current frequently, and to open and close the overload current, which is mainly used to control the power supply of the electric forklift. The price of the electric forklift is mainly related to the quality of the component. Then let's take a look at the selection method of electric forklift contactor.
1. If you are controlling AC loads, you should choose AC contactors, and if you are controlling DC loads, you should choose DC contactors;
2. The use category of the electric forklift contactor should be consistent with the nature of the load;
3. Pay attention to the rated working voltage of the main contact, which should be greater than or equal to the voltage of the load circuit;
4. The rated working current of the main contact of the electric forklift contactor should be greater than or equal to the current of the load circuit. The rated working current of the main contact of the contactor is under the specified conditions (rated working voltage, use category, operating frequency, etc.) ) The current value that can work normally, if the actual use conditions are different, this current value should also change accordingly;
5. The rated voltage of the attraction coil should be consistent with the control circuit voltage. The electric forklift contactor should be able to pull in reliably when the coil rated voltage is 85% or more.
In order to maintain the long-term stable working state of the electric forklift, it is necessary to select the appropriate electric forklift contactor. Through the use of the above methods, you can help you choose the right contactor.
