vacuum circuit breaker is a type of circuit breaker that uses vacuum interrupters to extinguish an electrical arc. It is commonly used in medium to high voltage applications where high currents are involved.

The basic construction of a vacuum circuit breaker consists of fixed and moving contacts, a vacuum interrupter, and a spring operating mechanism. When the circuit breaker is closed, the contacts are pressed together, allowing the electrical current to flow. When the circuit breaker is opened, the contacts move apart, creating an electrical arc. The vacuum interrupter uses the vacuum inside the interrupter to extinguish the arc, preventing damage to the contacts and surrounding equipment.

Vacuum circuit breakers have several advantages over other types of circuit breakers, including high reliability, low maintenance, and fast interruption of short circuit currents. They are also more environmentally friendly than other types of circuit breakers, as they do not use any harmful gases or chemicals.

Vacuum circuit breakers are commonly used in power generation plants, transmission and distribution systems, and industrial applications.
