The Midwest Heavy Duty manual transfer switch provides reliable,
trouble-free transfer of power from the normal utility supplied
source, to a stand-by generator. This enables the user to maintain
power during utility down time periods. The “double throw” mech-
anism 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. Special
application models, with meter sockets or switched neutrals, are
also available.
Typical applications include poultry farms, 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.
