A medium-voltage power circuit breaker (MVPCB) is a circuit breaker that operates with voltages ranging from 2300 V to 69,000 V. The most common method of classifying these circuit breakers is by using their arc-quenching medium. MVPCBs are classified as air-magnetic, vacuum, oil, air-blast, and gas circuit breakers. See Figure 4.
This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks. The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant.
