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://lowvoltage-configurator.tnb.com/configurator/#/config/tmax_xt.
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 65 kA.
10. For 480 V: When designing UL508A panels, Article SB 4.2.3 Exception No. 3
allows the use of other manufacturers' current limiting inverse time circuit
breakers which have same voltage, current and interrupting rating, if I
peak
and
I
2
t are the same or less than the ABB specified circuit breaker.
11. For 480 V: Non-current limiting inverse time circuit breakers must not be used.
12. Alternative circuit breakers can be used if they meet certain characteristics.
For acceptable breakers see
Alternate Fuses, MMPs and Circuit Breakers for
ABB Drives (3AXD50000645015 [English])
