The main function of a vacuum contactor is simply to make and break the connection between the power source and the load. It is specifically designed for medium voltage applications, typically ranging from 1.14kV to 40.5kV. The use of a vacuum ensures that the arc typically generated during the switching process is eliminated, which extends the life of the contactor and reduces maintenance requirements.


Here are some of the benefits of using a vacuum contactor:


  • Arc Suppression: The vacuum effectively suppresses the electrical arc that can occur when contacts within a contactor open or close, thus preventing damage to the system.

  • Longevity: Vacuum contactors tend to have a longer lifespan compared to other types of contactors because the contacts are less susceptible to wear and degradation due to the lack of atmospheric conditions that could lead to oxidation.

  • Reliability: The sealed vacuum environment provides consistent performance over a wide range of operating conditions and reduces the likelihood of faults, leading to increased reliability.

  • Safety: By containing the contacts within a vacuum, the risk of fire and explosion is significantly reduced, which enhances the overall safety for operators and equipment.

  • Compact Design: Vacuum contactors are generally smaller than their air-insulated or oil-insulated counterparts, which saves space in electrical panels and switchgear.

  • Low Maintenance: With fewer parts exposed to wear and no need for gases or oils that require regular replacement or maintenance, vacuum contactors are low maintenance.

  • Noise Reduction: The operation of a vacuum contactor is quieter, which is beneficial in environments where noise pollution is a concern.


Vacuum contactors are commonly used in industrial motor starters, transformer switching, capacitor switching, and other applications where efficient, reliable high-voltage switching is required.
