MEDIUM VOLTAGE VACUUM CONTACTORS & STARTERS  

 

Greenstone USA medium voltage Vacuum Contactors and Starters are used in many different applications such as: Mining, petroleum, control electric loads such as electric motors and many others.

 

Our medium voltage Vacuum Contactors are supplied with our state of the art Vacuum Interrupters that allow the moving contact to be closed and pulled open from the outside without leaking air into the bottle, this is very critical when you are using Vacuum Contactors in flammable areas.

 

Below is a list of our medium voltage Vacuum Contactors we manufacture, if you do not find the Vacuum Contactor you are looking for on the please contact us with your Vacuum Contactor requirements and we custom build one to fit your application.
