Description
Eaton’s wallmount manually
operated transfer switches
are designed for a variety of
standby power applications
for critical loads. In the event
of a primary power source
interruption, the user can
manually transfer the load
circuits to the standby power
source. Once primary power
has been restored, the user
can manually transfer the
load circuits back to the
primary power source.
Application Description
Manual transfer switches
cover applications ranging
from 30 to 1000A through
600 Vac for standard manual
configurations and open
transition.
Manual transfer switches
may be applied for those
application where a manually
initiated and manually
operated transfer is suitable.
The front door of the switch
must be opened to operate
the manual handle. The
design comes standard with
a deadfront design, allowing
safe manual transfer under
load. Should an application
require a service entrance
rating, then a non-automatic
or automatic design needs to
be selected.
