Product Description:Vacuum Circuit Breaker is a kind of indoor switchgear, which uses vacuum as the arc extinguishing medium. It is suitable for 50Hz/60Hz rated frequency. The rated operation sequence is 0.3s-180s-180s. Its rated short-circuit opening current could be 50kA/ 63kA/ 80kA/ 100kA/ 125kA/ 160kA/ 200kA/ 250kA/ 315kA/ 400kA, while the rated short-circuit closing times is 20 times. The rated short-circuit closing current is 25kA/ 31.5kA/ 40kA/ 50kA/ 63kA/ 80kA/ 100kA/ 125kA/ 160kA/ 200kA. Vacuum Circuit Breaker, also known as VCB, has the advantages of small volume, light weight, quick make-and-break operation, and long service life. It is widely used in power plants, substations, industrial and mining enterprises.
