VS1-12 type vacuum circuit breaker is a kind of indoor high voltage switch device which is used in the AC Three-phase power system of frequency 50HZ,rated voltage 12KV to be the protection and control unit. Because of the special superiority of vacuum circuit breaker, especially suitable for applications that require frequent operation at rated operating Current or multiple open short-circuit breaking current location. It 1s especially suitable to the place requiring frequent operations.
VS1-12 type vacuum circuit breaker adopts fixed installation, which is mainly used in the fixed switchgear. It can be used alone or used in ring network power supply system, box-type variable system and non-standard power supply system to protect and control the Transmission and distribution line.
