Midwest Electric Manual Transfer Switches

The Midwest Heavy Duty manual transfer switch provides reliable, and trouble-free transfer of power from the normal utility supplied source to a stand-by generator enabling the user to maintain power during utility down time periods. The "double throw" mechanism helps prevent dangerous backfeeding of generator power into the utility system. The Midwest transfer switch is designed to be fully operational and switchable at full rated capacity.

The Midwest Transfer switch is available in single phase and three phase configurations, and in ratings through 600v. Typical applications include poultry farms and dairy farms, ventilation in animal confinement buildings, crop drying, and anywhere an extended loss of normal power service would result in severe loss, damage or inconvenience.
