• VBI-C-24kV Side Mounted Vacuum Circuit Breaker With VBI Spring Operating Mechanism

  VBI-24 indoor medium-voltage sealed vacuum circuit breaker is suitable for air-insulated indoor switches and is used for control and protection in power grids with AC and rated voltage of 24KV and below. Vacuum circuit breakers are used in frequent It has extremely excellent performance in operation and situations where the circuit breaker current needs to be opened, fully meets the requirements of automatic closing, and has high reliable operation and service life.

  The operation mechanism of VBI-24 side mounted type vacuum circuit beaker is used spring to storage energy, which can be operated by two ways, manual or electrical. The characteristics are accordance with GB1984-89 <AC High Voltage Circuit Breaker>, JB3855-96<10kv Indoor High Voltage Vacuum Circuit Breaker General Technical Specifications>, Relevant Provisions of IEC56 standard.
