The working principle of the contactor: Upon energization, the circuit with current will create a magnetic field and generate sufficient magnetic adhesion to overcome counterforce, close armature and connect the contacts.
When the coil voltage dies out or reduces to a certain value(i.e. at the state of voltage release), for the flux generated at the end face of the armature decreases, the magnetic adhesion becomes weaker than the counterforce generated by the reaction spring, contact spring, etc.
Under the counterforce, the armature will be released and free from the field yoke, and then the contacts will be disconnected.
First confirm whether the product voltage, current, frequency and use category meet the requirements before use;
Second connect the control circuit first for no-load operation test and
then connect the load in case of no abnormality;
Third regularly tighten the terminals and remove the deposited dust;
Forth don't make the foreign matters fall into the product.
