VKC-12 Indoor high voltage series vacuum circuit breaker

OVerview

VKC-12 indoor high voltage series vacuum circuit breaker is suitable for three-phase AC power system with rated voltage of 12KV and frequency of 50Hz. It can be widely used in electric power, water conservancy, communication, industry, new energy, petrochemical, transportation, infrastructure and other industries. The switch operating mechanism adopts an integrated modular mechanism. The vacuum interrupter and the main conductive circuit are directly sealed in the epoxy resin pole by the mature APG process to form a solid-sealed insulation method to protect the vacuum interrupter and the main circuit components from being affected by collision, dust and condensation. It is suitable for places with frequent operation or multiple interruption of short-circuit current, especially for places with harsh environmental conditions.

VKC-12 indoor high voltage series vacuum circuit breakers meet the standards of GB1984 "High Voltage AC Circuit Breaker, GB/T11022"High Voltage Switchgear and Control Equipment Standard Common Technical Requirements", DL/T403"High Voltage Vacuum Circuit Breaker Ordering Technical Conditions"standards Requirements, and meet the relevant requirements of standards such as IEC62271-100.
