Vacuum Contactors and Starters

Eaton’s Vacuum Contactors are designed for starting and controlling three-phase, 50/60 Hz, AC motors. These contactors are built in several versions — the nameplate on a specific contactor states the authorized ratings. These applications include full voltage control of three-phase squirrel cage motors, primary control of low voltage wound rotor motors and circuit switching for low voltage capacitors for power factor improvement.
