Vaccuum Circuit Breaker

Vaccuum circuit breakers have minimal arcing (as there is nothing to ionize other than the contact material), so the arc quenches when it is stretched a very small amount (<2–3 mm). Vacuum circuit breakers are frequently used in modern medium-voltage switchgear to 35,000 volts.

The vacuum circuit breakers used in our Metal Clad Switchgear are of the product range NVL…F. They can be used for a rated current of up to 2500A and a rated operating voltage up to 24KV.
