1. Drives that have an enclosure minimum volume listed must be mounted in an
enclosure ≥ enclosure minimum volume specified in the tables above.
2. When multiple drives that have an enclosure minimum volume specified are installed
in the same enclosure, minimum volume of the enclosure is determined by largest
enclosure minimum volume of the drives to be placed in the enclosure, plus the
volume(s) of each additional drive. i.e. for the 480V R6 and R3 drive select enclosure
with the volume ≥ 53703+1011 = 54714 in
3
.
3. For UL Open Type, UL Type 1 or UL Type 12 drives that have a minimum enclosure
volume indicated with ¤, no minimum enclosure volume is required but the drive
must be mounted inside an enclosure.
4. If combining a drive with an enclosure minimum volume specified and others with
an enclosure minimum volume indicated with ¤, start with the largest specified
enclosure minimum volume listed and add the drive volumes for the other drives.
5. If you are only mounting drives with no enclosure minimum volume specified, you
have no restrictions on the enclosure size, but follow air clearances specified in the
drive HW manuals for sufficient ventilation around each drive.
6. UL Open Type, UL Type 1 and UL Type 12 drives can be used inside of the
enclosure. Use drive volume for all three types listed in the table when installing
multiple drives in the enclosure.
7. The ABB circuit breaker part number listed in the table is a base part number.
• Symbol α represents 80% or 100% allowable continuous current. Options
allowed are U, Q, C and D.
• Symbol β represents the number of poles for the breaker. Options allowed are
3, and 4.
• Symbol # represents trip units. Trip units allowed include A thru C, E thru L, P
thru Z. If using Ekip breakers, set the overload current of the circuit breaker
equal to or less than the value shown in the “CB Maximum Current” column in
the tables above.
• The digits indicated with an “*” represent accessories for the breakers and have
no impact on the drive UL listing or performance or rating of the breaker.
• For the ABB circuit breaker configurator refer to: https://lowvoltageconfigurator.

8. Ratings in the tables are maximum for the given circuit breaker frame size. Breakers
of the same frame size and interrupting rating with lower current ratings are also
allowed.
9. Using a circuit breaker with a lower KAIC rating is not allowed even if the available
SC current is less than 65kA.
230V drives were tested with ABB inverse time circuit breakers rated at 65kA and
240V.
