What is A Vacuum Contactor?

vacuum-contactor1

A vacuum contactor unit is an electrical device that contains contacts in a sealed environment called a vacuum bottle. This sealed vacuum interrupter, when the switching takes place, allows for a fast, safe, and clean make or break action of the contacts in harsh, dirty surroundings. 

One side of the vacuum contactor is movable, while the other side is fixed since its primary function is to make or break the connection between the load and the power source. Once the AC vacuum contactor is energized, the generated electromagnetic force pulls the movable contact to the fixed contact; then, the spring pulls them apart once de-energized. This operation is contained within the vacuum bottle, which has the arc and keeps contaminants outside.

Which industries can utilize vacuum contactors?

Compared to vacuum circuit breakers, vacuum contactors are smaller and safer for higher voltages. In addition, since medium voltage vacuum contactor function as an automatic switcher to connect or disconnect the AC and DC main circuit with a load or power control circuit, they can be applied to different industries. 

They are widely used in:

Coal Mines

Among the uses of vacuum contactor, the coal mining industry benefits the most due to the hazardous nature of the mining industry. Reliable power switching and motor starting are crucial in this industry, and vacuum contactors help manage motors in underground mining equipment.

Electricity

Medium voltage contactors have long life spans while functioning at a very high capacity. This is why medium voltage vacuum contactors are widely used in electrical generators for making or breaking the connector of power source and loads.

Commercial and Industrial Buildings

Vacuum contactors are often used to provide central control of large lighting installations, such as an office building or retail building. This is not just to regulate but also to reduce power consumption.

Metallurgy

In the metallurgy industry, a high voltage is necessary for welding optimization. Vacuum contactors are essential in the operation process because they can withstand a high voltage after experiencing short-circuit conditions.

Textiles

Medium voltage contactors are used to provide central control of electrical sources by making or breaking their connection. Also, they regulate and reduce power consumption, the reason why it is widely used in manufacturing industries, like the textile industry.

Incineration Plants

Medium voltage contactors extend to incineration plants because of their hazardous nature. This industry needs a reliable power switching and motor starting to help manage the incineration machines in the facility.
