Vacuum Circuit Breakers VCB Certification


About Vacuum Circuit Breakers VCB

A Vacuum Circuit Breaker (VCB) is an electrical switching device that uses a vacuum to interrupt the current in the event of an overcurrent or fault. It is a type of high-voltage circuit breaker that is used in medium-voltage and high-voltage electrical systems.

The main components of a VCB include:

Vacuum interrupter: a sealed container filled with a vacuum, which is used to interrupt the current
Operating mechanism: a mechanical device that is used to open and close the contacts of the vacuum interrupter
Control and protection system: a system that is used to control and protect the VCB, including sensors, trip units, and other devices
VCBs are considered to have several advantages over other types of circuit breakers, such as air-blast and SF6 circuit breakers, such as:

High reliability and durability: VCBs have a long service life and are less likely to fail than other types of circuit breakers
Low maintenance: VCBs require less maintenance than other types of circuit breakers
High breaking capacity: VCBs can handle high levels of current and can interrupt high-energy faults
Good performance at high altitude: VCBs are not affected by the decrease in air density at high altitudes, unlike other types of circuit breakers.
VCBs are widely used in medium-voltage and high-voltage electrical systems, such as substations, power plants, and industrial facilities. They are commonly used for applications such as switchgear, protection and control, and motor control centers.
