A circuit breaker is a device that stops an electric circuit to prevent inappropriate current from flowing due to a short circuit, which is usually caused by an overload. Its main function is to interrupt current flow when a fault is detected. Circuit breakers protect electrical systems from harm caused by over-currents & short circuits.

Abstract. Vacuum circuit breakers are generally operated with an operating mechanism with smaller operating energy as compared with those of other types of circuit breakers, because the vacuum interrupter employs disc-shaped "butt" contacts instead of finger-shaped contacts often used for SF 6 gas interrupter.

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.
Several types of de vacuum circuit-breakers were developed for commutating high-power inductive energy storages with switched currents of 1.5-50 kA and voltages of 30-200 kV.
The five universal circuit breaker components are: Contacts – Allows the current to flow through the circuit breaker when closed. Arc extinguisher – Extinguishes an arc when the circuit breaker interrupts a fault. Trip unit – Opens the operating mechanism in the event of a prolonged overload or short circuit.

Axial blast circuit breakers are well-suited for Extra High Voltage (EHV) and Ultra High Voltage (UHV) applications. In this type of circuit breaker, a high-pressure air blast is directed longitudinally, aligning with the arc. To mitigate transient over-voltages, resistance switching is implemented.
A circuit breaker is an electrical switching device designed to protect electrical systems from damage caused by excessive current or electrical faults. Its main function is to interrupt the flow of electricity when a fault occurs, preventing potential hazards such as electrical fires, equipment damage, and electrical shocks.
The early developers of vacuum circuit breakers underestimated the advantage of vacuum in the form of the ability to operate with small gaps, which allowed for more energy efficient actuators.
