Working Principles of a Vacuum Circuit Breaker. Since circuit breakers typically protect against overcurrent and a short circuit, they use a thermal and magnetic trip to detect each. When the circuit trips, it creates a chain of events inside the insulating medium. In the case of a VCB, the insulating medium is a vacuum.

Principle of Energy Storage Switch. The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the

.A circuit breaker is a switching device that interrupts the abnormal or fault current. It is a mechanical device that disturbs the flow of high magnitude (fault) current and in additions performs the function of a switch. The circuit breaker is mainly designed for closing or opening of an electrical circuit, thus protects the electrical system from damage.
