Ampgard 7.2 kV arc-resistant medium-voltage motor control
Eaton's Ampgard arc-resistant medium-voltage motor starters are designed to safely contain and redirect exhaust gases in the event of an arc flash incident. Built in an arc-resistant Type 2B enclosure for the strength needed to resist the forces of arc blasts up to 50kA. Ampgard arc-resistant provides enhanced safety from the front, sides and rear of the enclosure, even with the control doors open.

Ampgard, the name motor applications rely on
Eaton has been an industry leader for more than 50 years, providing UL 347 certified medium-voltage control. When it comes to controlling and protecting medium-voltage motors, the Ampgard family is the premier high-performance choice.
Money saving double-bus design
When close-coupling Ampgard starters with medium-voltage drives for synchronous transfer applications the double bus eliminates external cables and associated accessories required to connect motor-select and bypass starters. Material and labour savings can be upwards of $25,000 for a four-motor system.
Remote operator for enhanced safety
The Ampgard Remote Operator (ARO) for the starter isolation switch that, when mounted on the front of the starter, allows personnel to safely open and close the switch from outside the arc flash boundary.
Integrated control gear streamlines multi-configuration line-ups
