The series JCZ5-12kV/400A (vacuum switch)f high-voltage vacuum contactor are suitable for the distribution system of metallurgy, mine, petro-chemistry and building, to control the equipments used eletricity such as high-voltage motor of 12kV or under 12kV, transformer and capacitive loading etc. Especially suitable for frequent operation domain. Because of its small volume, light weight and packaged design of upper and lower arrangement, prevalented in the world. It is convenient to use and maintain, and is easy to form the complete equipment of F-C loop.
