Three-phase AC contactor has several terminals that have a role
The power is applied and the contact point is disconnected after power failure
How to connect, first of all should know the principle of AC contactor. He is using external power to the coil, resulting in electromagnetic fields
Output and input are corresponding, it is easy to see. If you want to add self-locking, then you also need to output from the terminal to a terminal connected to the control point above
Hello, the general three-phase contactor a total of 8 points, three input, three output, there are two control points.
