Product Summary

This new series of Generac Automatic Transfer Switches with Integrated Load Centers is designed for use with single phase generators that utilize an Evolution™, PowerZone™ 200, or Power Zone™ 410 Controller. These 300 and 400 Amp open transition switches are single phase service entrance rated configurations. This series includes Generac’s whole-house surge protection device (SPD), which is built into the transfer switch.
