Main technical parameters for VS1-12 vacuum Circuit Breaker

 

Indoor high voltage vacuum circuit breaker VS1-12 is indoor switchgear equipment with 3phase, AC ,50(60)HZ, rated voltage 12KV.

The prduction of this series shall be in conformity with GB1984,GB3309,JB3855,DL/T403 and relative IECstandard.

Under normal operation and within the rated technical parameter, it can be operated in safety and reliable, at same time , it can be operated frequently with AC or DC, also it can be operated by manual.

In the switch cabinet, the product can be installed by means of fixed or withdrawable installation, the main electrical circuit installation adopts the integrated solid sealed column to realize the circuit breaker with the advantages of miniaturization,high reliable and no maintenance.
