Product Description
Eaton’s wallmount non-
automatic transfer switches
are designed for a variety of
standby power applications
for critical loads.

power source interruption,
the user can manually

the standby power source
through the use of an
external pushbutton. Once
primary power has been
restored, the user can
manually transfer the load
circuits back to the primary
power source through the
use of an external
pushbutton.
