5. A fuse of a different class can be used at the high fault rating where the
I
peak
and
I
2
t
of the new fuse is not greater than that of the specified fuse.
6. UL listed 248 fast acting, time delay, or high speed fuses from other manufacturers
can be used if they meet the same class and rating requirements specified in the
rules above.
7. When installing a drive, always follow ABB installation instructions, NEC requirements
and local codes.
8. Alternative fuses can be used if they meet certain characteristics. For acceptable
fuses, see the manual supplement (
Circuit breakers (IEC)
Contact ABB.
Circuit breakers (UL)
■
ABB inverse time circuit breakers
The drives are suitable for use on a circuit capable of delivering not more than 65 kA
symmetrical amperes (RMS) at 480 V maximum when protected by circuit breakers in
the tables below.
Additional fuse protection is not required when using the circuit breakers herein.
Circuit breakers are not required to be in the same enclosure as the drive.
For more information see the manual supplement (
[English])
1. For UL Type Open, Type 1 or UL Type 12 drives no Enclosure Minimum Volume
is required but the drive must be mounted inside an enclosure.
2. If combining a drive with no Enclosure Minimum Volume and others with an
Enclosure Minimum Volume specified, start with the largest specified Enclosure
Minimum Volume listed and add the drive volumes for the other drives.
3. When only mounting drives with no Enclosure Minimum Volume specified, there
are no restrictions on the enclosure size. Always follow air clearances specified in
the drive hardware manuals for sufficient ventilation around each drive.
4. UL Type Open, Type 1 and Type 12 drives can be used inside of the enclosure.
Listed drive volumes in the table apply for all three UL Types when installing multiple
drives in the enclosure.
5. 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.
