Floor-Standing Magnum Transfer Switches
Product Description
Eaton’s Magnum transfer
switches are designed for a
variety of standby power
applications for critical and
noncritical loads. They
monitor both Source 1
(Normal) and Source 2
(Emergency) power sources.
In the event of a Source 1
power interruption, these
switches will automatically
transfer the load circuits to
the Source 2 power source.
Once Source 1 power source
has been restored, the
process is automatically
reversed.
Application Description
The Magnum family of
transfer switches covers
applications ranging from 200
to 5000A through 600 Vac.
Some of the applications are:
automatic or non-automatic
configurations, open or
closed transition and standard
or rated suitable for use as
service entrance. They are
designed for applications
where total system
coordination must be
accomplished
while achieving
a high level of Withstand,
Interrupting, and Closing
performance.
Drawout construction is
available for applications,
such as critical life-support
systems, where preventive
maintenance, inspection
and testing must be
accomplished while
maintaining continuity of
power to the load.
