XK VD4 VS1-12 11KV 630A 1250A 1000A 1600A 800A 2000A 2500A 3000A Indoor Auto Drawable electrical Vacuum Switch
High quality 24KV Indoor three-phase ac 50-60HZ vacuum circuit breaker
Product Description
A circuit breaker is a device that, interrupts an electric circuit to prevent unwarranted current, caused by a short circuit, typically resulting from an overload. Its basic functionality is to interrupt current flow after a fault is detected. To know more about Circuit breakers read this article Types of Circuit Breaker and Its Importance. A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in vacuum medium. The operation of switching on and closing of current carrying contacts and interrelated arc interruption takes place in a vacuum chamber in the breaker which is called vacuum interrupter.
Vacuum Circuit Breaker
The Vacuum interrupter technology was first introduced in the year
of 1960. But still, it is a developing technology. As time goes on,
the size of the vacuum interrupter has reduced from its early
1960’s size due to different technical developments in this field
of engineering.
