Air circuit breakers are commonly employed for applications with lower voltages. They can be quickly shut down to handle high fault currents as well as stopping the power supply for any associated appliances. They function by forcing an arc into a chamber specifically designed to offer adequate cooling. In addition, they could use to test…

Vacuum circuit breakers (VCB) operate fast, making them perfect for fault clearance. They also require very little maintenance. When the breaker operates, the moving and fixed contacts separate to create an arc. This arc is quickly extinguished because metal vapors, electrons, and ions generated during arcing rapidly condense over the contact surfaces. This quick recovery…
