ISO9001 400A AC 7.2KV High Voltage Vacuum Contactor JCZ5

Product Name:   ISO9001 400A AC 12KV High Voltage Vacuum Contactor JCZ5

Type: Vacuum Contactor

Vacuum contactors utilize vacuum bottle encapsulated contacts to suppress the arc. This arc suppression allows the contacts to be much smaller and use less space than air break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used fairly extensively in dirty applications, such as mining.

Vacuum contactors are only applicable for use in AC systems. The AC arc generated upon opening of the contacts will self-extinguish at the zero-crossing of the current waveform, with the vacuum preventing a re-strike of the arc across the open contacts. Vacuum contactors are therefore very efficient at disrupting the energy of an electric arc and are used when relatively fast switching is required, as the maximum break time is determined by the periodicity of the AC waveform.

The series JCZ5-12J(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 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.  

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