Vacuum contactors like KVTV of production of NPP-Elektrodinamika - are intended for switching of receivers of electric energy of 3 phase networks on the rated voltage of 6 kV and 10 kV. Kontaktora have natural air cooling and provide working capacity in categories of application AS-3, - AS-4 and other modes according to GOST 11206.

Are intended for work in the following modes:

 - -> long -
 - -> preryvisto-prodolzhitelnom-
 - -> short-term -
 - -> repeated and short-term. -

Are used:
 - -> in transformer devices of input -
 - -> for switching of electric motors -
 - -> in compressor and pump stations -
 - -> in other switches.

Dignity of vacuum contactors

 - -> lack of an open electric arch -
 - -> lack of need for service of the main contacts -
 - -> low level of noise at inclusion and shutdown kontaktora-
 - -> the reduced dimensions in comparison with air kontaktorami-
 - -> the raised resource on limit currents of switching.
 -  -

Vacuum contactors like KVTV of production of NPP-Elektrodinamika - are made according to TU U 27.1-31633409-002:2012 and are certified in the State System of Sertifikatsii UKRSEPRO.
