Description

VSG-12 type Indoor high voltage vacuum circuit breaker used spring to storage energy. The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker
  • Product Detail
  • Technical Parameters

VSG type indoor high-voltage vacuum circuit breaker is suitable for switching various loads of different natures and frequent operations in power systems with three-phase AC 50Hz and rated voltage of 7.2kV-40.5kV. It can be used in industries, mining, enterprises, and power plants. And for the protection and control of electrical equipment in substations. It can be equipped with KYN28A and other mid-mounted handcart switch cabinets, and can also be equipped with XGN fixed switch cabinets. The VSG indoor high-voltage vacuum circuit breaker complies with the national standards GB1984 “AC High-voltage Circuit Breaker”, JB/T3855 “3.6~40.5kV Indoor AC High-voltage Vacuum Circuit Breaker” and IEC60056 “High-Voltage AC Circuit Breaker” standards.
