Start your 15kV motor with a product specifically designed for motor application

Traditionally 15 kV motors have been started with medium-voltage breakers. Now you can start your motor with a vacuum starter, saving space while reducing maintenance requirements.

Remote operator for enhanced safety

The Ampgard Remote Operator (ARO) for the starter isolation switch when mounted on the front of the starter allows personnel to safely open and close the switch from outside the arc flash boundary.
