Tips: Reasons for the contacts of contactor being unable to close after powering on

1. Power supply circuit of the coil shorts.
2. Coil circuit breaks.
3. Coil's control voltage is too low.
4. The contactor's coil has burnt out, thermal deformation of coil skeleton makes the iron core
5. unable to be sucked to a proper place, thus the contact can't close.
6. Adhesion of main contact.
7. A foreign body or hard spots in the armature.
8. Main contact dislocates (mainly for large contactor, bridge type contact).
9. Auxiliary contact is not well installed.
