Application Guide: Motorpact Medium Voltage Motor Controller

Square D® Motorpact™ Medium Voltage (MV) motor controllers provide control for 2300–7200 V induction (squirrel cage) motors, continuing our tradition of offering superior reliability combined with numerous operational benefits. These versatile controllers feature state-of-the-art vacuum technology with minimal current chopping (see "Section 5–Contactors" on page 18).

The Motorpact design reduces the number of internal electrical power connections, allowing for increased power throughput, reduced heat rise, and reduced controller maintenance.

Motorpact controllers have drawout contactors in one-high construction. The vacuum contactors are available in 200 A, 400 A, 450 A, and 720 A ratings, either electrically or mechanically held. Schneider Electric can provide Indoor Type 1/1A (with gaskets) and Outdoor Type 3R enclosures.
