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
and 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).

Miniature circuit breakers (IEC)

If you use a miniature circuit breaker for the short-circuit protection of the drive,
install the drive into a metal enclosure.
Note: Miniature circuit breakers with or without fuses have not been evaluated
for use as short-circuit protection in North American (UL) environments.
The protective characteristics of the circuit breakers depend on the type,
construction and settings of the breakers. There are also limitations pertaining
to the short-circuit capacity of the supply network. Your local ABB representative
