Tips: Reasons for AC magnetic contractor noise

  • The over travel of the AC contactor contact is too large, resulting in insufficient contact pressure between the moving and static iron cores.
  • The contact springs share the pressure or the release reaction spring force is too large, causing a certain gap between the moving and static iron cores during operation.
  • The clamping screws of the moving and static iron cores are loose, the movable parts are not properly matched, the moving and static iron cores are misaligned when they are sucked in, and the entire surface cannot be contacted.
  • The short-circuit ring is broken or missing. Because the dynamic and static iron cores collide too violently during the pull-in, or the mechanical life ends, the short-circuit ring is broken or lost, resulting in excessive noise.
