Function: The main function of the vacuum contactor is to control the current in the circuit. It is used to make and break electrical connections, allowing or interrupting electrical current. Vacuum contactors are commonly used in applications that require frequent switching, such as motor control, capacitor bank switching, and power distribution systems.
Structure: The vacuum contactor consists of a set of static contacts and moving contacts installed in a vacuum-sealed casing. When the contacts are closed, current flows through them. When the contacts open, an arc is generated due to the interruption of the current flow. The vacuum inside the contactor helps to extinguish the arc quickly and efficiently.
Advantages: Vacuum contactors offer several advantages over other types of contactors. They last longer because the vacuum environment reduces contact wear and degradation. They also have excellent electrical insulation properties, high switching capacity and low maintenance requirements. Additionally, vacuum contactors are known for their reliable performance and ability to handle high inrush currents.
Applications: Vacuum contactors are commonly used in a variety of applications including motor control centers, power factor correction systems, capacitor banks, and power distribution systems for applications requiring frequent switching and high reliability.
