I-vacuum circuit breaker ingeyokukhiqiza ugesi kanye nezindawo zesiteshi esincane njengezinhloso zokulawula nokuvikela ugesi, futhi iwuhlelo lokusabalalisa kumabhizinisi ezimboni nezimayini, ifekthri yamakhemikhali kaphethiloli, i-metallurgy, kanye nomphakathi. Hlangana nezidingo zokulawula nokulinganisa, futhi uqaphele isilawuli kude nokuqapha. Umkhiqizo unokwethenjelwa okuphezulu, izici zokunakekelwa kwamahhala nempilo ende, ifaneleka kakhulu ukusebenza njalo, izimo eziphula ngokuphindaphindiwe, njenge-short-circuit current yaleyo ndawo.
