• VCB stands for Vacuum Circuit Breaker and are mainly used in circuit breakers that use medium to high levels of voltage, where the arc quenching occurs in a vacuum.<\/li>\n
• In this circuit breaker, the fixed and moving contact is enclosed in a permanently sealed vacuum interrupter.<\/li>\n
• The arc is extinct as the contacts are separated in high vacuum.<\/li>\n
• It is mainly used for medium voltage ranging from 11 KV to 33 KV.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
