    Tips: How to install vacuum AC contactor?

    1. 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.
    2. When installing and wiring, do not lose the parts inside the vacuum AC contactor to avoid jamming or short-circuit failure.
    3. The fixing screws should be tightened to prevent vibration during operation.
    4. 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.
    5. The contacts of the vacuum AC contactor should be regularly cleaned and kept clean, but oiling is not allowed.
