What is working principle of VCB?
Working Principle of Vacuum Circuit Breaker: The working principle of the Vacuum Circuit Breaker is that once the circuit breaker is opened inside the contact vacuum, an arc can be generated between the contacts by ionization of the metal vapor in the contact.
What is VCB vacuum circuit breaker?
VCB stands for vacuum circuit breaker. This type of circuit breaker uses vacuum media for quenching the arc. In VCB vacuum is used because the dielectric strength of the vacuum is far better than any type of medium. The vacuum is the superior dielectric medium of extinct using the arc compared to other mediums.
Why do we use VCB?
Vacuum Circuit Breaker(VCB) is used for protecting electric systems from faults such as Short-circuit current generated in the electrical systems. VCBs are installed with Vacuum interrupters which break supply in case of fault and it uses vacuum as a medium to quench the arc.
What are the parts in VCB?
Construction of Vacuum Circuit Breaker Their construction is mainly divided into three parts, i.e., fixed contacts, moving contact and arc shield which is placed inside the arc interrupting chamber.
What is the difference between VCB and OCB?
VCB are costlier then OCB almost Twice in price.In VCB male and female contact are horizontal and if there is uneven floor there is danger of chattering due to misalignment may result damaging of contacts.
What are the benefits of using RMUS?
