12KV 630-2000A Vacuum VCB Circuit Breaker Withdrawable High Stability

Voltage:	12-24KV	Current:	630-2000A
Breaking Current:	25KA Max	Type:	Withdrawable
Standard:	GB,ISO,IEC

VS1-Series circuit breaker features high stability and high reliability

"High-Voltage Vacuum Circuit Breaker" is named because both the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are vacuum; Advantages, the application in the distribution network is more popular.

The circuit breaker is identified by some national standards and international relative standards, such as GB1984,GB/T11022,DL/T403 and IEC62271, etc.
