A vacuum circuit breaker is an electrical switch used to control and protect electrical circuits. It works by creating a vacuum in the interrupter chamber, which extinguishes the arc formed when the circuit is interrupted. This technique provides a reliable and efficient method of breaking and making electrical connections.

Vacuum circuit breakers are commonly used in medium and high voltage applications such as power distribution systems, industrial plants and substations. They offer several advantages over other types of circuit breakers, including faster operating speeds, higher breaking capacity, longer service life and lower maintenance requirements. In addition, vacuum circuit breakers are more resistant to environmental factors such as moisture, dust and pollution.

Vacuum circuit breakers are a reliable and efficient solution for controlling and protecting electrical circuits. They provide a safe and effective method of interrupting electrical current, ensuring the safety and reliability of electrical systems.
