The Eaton Drawout Magnum Switch
should be considered for any systems
requiring either greater redundancy,
easier maintainability, or where true
selective coordination is desired.
The Eaton Drawout Magnum Switch
provides the capability to isolate either
of the two power sources (Source 1 or
Source 2) and its associated logic, while
maintaining power to the load.
Each switching section is independent
and can be replaced either with a spare
switch, or for less critical replacement
needs, a replacement unit is available
from the factory.
