Tips: Reasons for the contacts of contactor being unable to separate after powering off

  1. Control line of the coil is too long, the residual voltage is too large due to the influence of lead capacitance, which is enough to maintain a close situation for the iron core. As a result, the contacts can't be separated.
  2. Coil of the contactor has burnt out, deformed coil skeleton seizes the movable iron core, which makes it unable to move, thus the contacts can't be separated.
  3. The contact has been fused.
  4. The contactor has auto-lock function, and the function is normal.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
