Tips: Advantages of ac vacuum contactors for sale on RDDLZ

RDDLZ ac vacuum contactor has strong arc extinguishing ability, good pressure resistance, high operating frequency, long life, no arc spray, small size, light weight, and long maintenance cycle. The process requirements for the vacuum interrupter of the ac vacuum contactor are very high. If the process is poor, the vacuum of the interrupter is easy to drop. If the contact material of the ac vacuum contactor is not good, the phenomenon of "intercepting over-voltage" will occur when the current is interrupted. That is, when the current is interrupted, due to the strong arc extinguishing ability of the vacuum interrupter, the arc current is not cut off naturally at zero crossing, but suddenly drops from a certain value of the current to zero, resulting in a high overvoltage. Intercepting over-voltage will endanger the safe operation of electrical equipment.

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.
