Molded Case Switches—Automatic Wallmount
Product Description
Eaton’s wallmount transfer
switches are designed for a
variety of standby power
applications for critical loads.
They provide flexibility,
reliability and value in a
compact package. In the
event of a primary power
source interruption, a transfer
switch provides an effective
means to transfer the load
circuits to an alternate power
source while reducing the
possibility of injury or
property damage.
Wallmount transfer switches
meet or exceed all industry
standards for endurance,
reliability and performance.
These breaker-based designs
can be applied with the
ATC-100, ATC-300 or
ATC-600 controllers.
Application Description
Suitable for emergency and
standby systems (all loads).
