Product Description
Eaton’s Magnum Transfer Switches
are designed for a variety of standby
power applications for critical and
non-critical loads. They monitor both
Source 1 (Normal) and Source 2
(Emergency) power sources. In the
event of a Source 1 power interrup-
tion, 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.
The Magnum family of transfer
switches covers applications ranging
from 200 to 5000 amperes (A) through
600 Vac. Some of the applications are;
automatic or non-automatic configura-
tions, 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 maintain-
ing continuity of power to the load.
Eaton Magnum Transfer Switches
meet or exceed all industry standards
for endurance, reliability, and perfor-
mance. They are listed under Under-
writers Laboratories UL 1008 Standard
for Transfer Switch Equipment. With
certain options, they also comply with
Source 2 and standby system require-
ments as defined in NFPA 99 for health
care facilities.
