When installing units for CENTERLINE 2100 Motor Control Centers
with the ArcShield rating, 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. The arc resistance rating can be found on the
ArcShield label on the vertical wireway door.
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.
