ASCO Automatic Transfer Switch Manufactured by Schneider Electric.
With an ATS you are protected 24 hours a day, seven days a week.
When the utility power fails, the ATS automatically starts the generator set and
transfers the load once the generator has reached proper voltage and
frequency. This happens in a matter of seconds after the power failure occurs.
As soon as the utility power has been restored, the ATS will automatically switch the load
back and, after a time delay, shut down the engine generator.

Designed to Fit Anywhere
The ASCO Automatic Transfer Switch, 300 series line represents the most compact design
of automatic power transfer switches in the industry. With space in electrical closets being
at a premium, the use of wall or floor mounted ASCO Transfer Switches assure designers
optimum utilization of space. All transfer switches through 2000 amperes are designed to
be completely front accessible; permitting the enclosures to be installed flush against the
wall while allowing installation of all power cabling and connections from the front of the
switch. Additionally, cable entrance plates are also standard on the 1600 and 2000 amperes
units to install optional side-mounted pull boxes for additional cable bending space.
