High Voltage DC Contactor Coil Schematic

Details

Tips: Fusion welding of the contactor due to electric shock, how to solve?

Possible causes of the fault:

short circuit of contactor on the load side.
Overload use of contactor contact.
There’s a foreign body or a metal particle on the surface of the contact.
Pressure of the contact spring is too small.
Poor contact of contactor's lines, which makes the contactor repeatedly pull in and release at a moment.

Maintenance method:

Power off at first, separate the welding contacts with a screwdriver, correct the contact surface and eliminate the short-circuit fault.
Replace with a large capacity and high quality contactor.
Smooth the contact surface with a steel file and remove foreign bodies.
Readjust the spring pressure.
Check the bad contacts of the coil control loop of the contactor, reconnect the loop or replace electrical components, ensure a good on-off situation.

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.
