Introduction :  

VS1 -12Series type indoor high voltage vacuum circuit breaker is rated voltage 12kV, three-phase AC 50Hz Indoor high-voltage switchgear ,apply for power stations, substations, and industrial and mining enterprises to control or   protection transmission and distribution systems , specially for the important high altitude breaking load and frequent operation place.  

Circuit breaker manufacturing accordance with our national standard GB1984-2003, DL / T403-2000<3.6 40.5kv="" indoor="" vacuum="" circuit="" breaker="" ordering="" technology="">; and the related IEC standards And reliable interlock function.  

Circuit breaker operating mechanism for the spring energy storage type, can use AC and DC energy storage operations, can also be used manually. 

Circuit breaker can be equipped with long life permanent magnetic actuator, mechanical life can reached 60000 times ,can be used for extremely Frequent operation place,

Circuit breaker designed to repackage the structure before and after, both can be used as a fixed installation unit, Can also be equipped with the chassis as used in the mounted unit.  

The use of environmental conditions:
