1. Fuses are required as part of the installation, are not included in the base drive
configuration and must be provided by others.
2. Fuses with a higher current rating than specified must not be used.
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
2
I 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 you install a drive, always obey ABB installation instructions, NEC
requirements and local codes.
8. Alternative fuses can be used if they meet certain characteristics. For permitted
fuses, see Branch Circuit Protection for ABB drives manual supplement
(3AXD50000645015).
