AC vacuum contactor outline and installation dimension (Unit: mm)

Tips: How to install vacuum AC contactor?

The vacuum AC contactor should generally be installed on a vertical surface, and the inclination should not exceed 5°. For AC contactors with heat dissipation holes, the heat dissipation holes should be placed up and down to facilitate heat dissipation.
When installing and wiring, do not lose the parts inside the vacuum AC contactor to avoid jamming or short-circuit failure.
The fixing screws should be tightened to prevent vibration during operation.
When metal beads appear on the surface of the contact due to electric arc, file and repair it in time. However, the oxide film produced on the surface of the silver and silver alloy contacts does not need to be filed because of the small contact resistance, otherwise the life of the contacts will be shortened.
The contacts of the vacuum AC contactor should be regularly cleaned and kept clean, but oiling is not allowed.

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.
