Vacuum contactors

MEDIUM VOLTAGE VACUUM CONTACTORS and Starters

Greenstone USA vacuum contactors are used to efficiently protect and control motors, switchgear, transformers, capacitor banks and breakers for many different applications. Our vacuum contactors are widely used in the gas, petroleum, Mining and many other industries where protection is needed. Our vacuum contactors are used to replace Joslyn Clark, Siemens, Toshiba and many other manufacturers.
