3. The UL listed fuses recommended by ABB are the required branch circuit protection
per NEC. Circuit breakers listed in section Circuit breakers (UL) are also acceptable
as branch circuit protection.
4. The recommended size or smaller UL listed 248 fast acting, time delay, or high
speed fuses must be used to maintain the UL listing of the drive. Additional protection
can be used. Refer to local codes and regulations.
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. Only 480 V R9 drives with serial numbers beginning 1204109256 when built in
Finland and beginning 22106xxxxx when built in the U.S. may be protected with
fuses other than Class T fuses.
9. Alternative fuses can be used if they meet certain characteristics. For acceptable
fuses, see the manual supplement (3AXD50000645015).
Circuit breakers (UL)
These drives are suitable for use on a circuit capable of delivering not more than 65 kA
symmetrical amperes (RMS) at 240 / 480 / 600 V maximum, when protected by
appropriate circuit breakers in the tables below. Additional fuse protection is not required
by UL when using circuit breakers herein. Circuit breakers are not required to be in the
same enclosure as the drive.
Notes below the tables must be followed when using these breakers.
