Vacuum Circuit Breaker (VCB) is an electrical switching device that uses a vacuum as the interrupting medium to extinguish the electric arc when a fault occurs in the electrical circuit. VCBs are typically used in medium-voltage applications (up to several thousand volts) and are often used in power generation, transmission, and distribution systems. The main advantage of VCBs over other types of circuit breakers is that they are very reliable and require very little maintenance. They are also more environmentally friendly than other types of circuit breakers because they do not use any harmful gases or liquids. When a fault occurs in an electrical circuit, the VCB interrupts the current flow by creating a high resistance path through the vacuum. This causes the current to be rapidly reduced to zero, which extinguishes the arc and breaks the circuit. VCBs are capable of interrupting both AC and DC currents and are designed to handle both short-circuit and overload conditions. Overall, VCBs are a very reliable and effective way to protect electrical systems from damage due to faults. However, they are typically more expensive than other types of circuit breakers and may not be suitable for all applications.
