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 does not
apply if that is done.
