ATTENTION: When installing units for CENTERLINE 2100 Motor Control Centers
(MCC) with ArcShield™ baffles, you must make sure you are installing a unit that
has the same arc resistance rating as the MCC in which it is being installed. Units
that are not rated for 100 ms arc duration must not be installed in a section that
is rated for 100 ms arc duration. The arc resistant rating will not apply if that is
done. The 0.5 space factor units and doors are not available in ArcShield units
with 100 ms arc duration designs and must not be used in 100 ms arc duration
rated MCC sections.
