General Description
VSG-C/12 type side installation indoor high voltage vacuum circuit breaker is applicable to 12kv power system, as a protection and control unit of power equipment, industrial and mining enterprises, it can be used for switching loads of various kinds and frequent operation, repeatedly breaking short-circuit current situation. The product adopts new type of circuit breaker, a VSG part can adopt the international brand of embedded pole, the vacuum interrupter and the main circuit part is fixedly sealed into a whole, protect the interrupter from collision, dust and gel image, strong ability to adapt to the environment, greatly reduces the cost of operation and maintenance. The real implementation of the product part of a maintenance free, low maintenance operation mechanism; operating mechanism and circuit breaker body design, after type test, E2 level, M2 level of mechanical electrical life.
VSG-C/12 type side installation 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 62271-100:2001High Voltage AC Circuit Breaker.
Applying Ambient Conditions
