The series JCZ5 of high-voltage vacuum contactor are suitable for the distribution system of metallurgy, mine, petro-chemistry.

The series JCZ5-7.2J(D) of 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 7.2kV or under 7.2kV, 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.  

Its holding method can be divided into two types:J type (mechanical holding)D type (electrical holding).
