Fuses (UL)
The UL Listed fuses in this manual are required for branch circuit protection and required
per NEC. The drives are suitable for use on a circuit capable of delivering not more than
100 kA symmetrical amperes (RMS) at 480 V maximum when protected by the fuses
described below.
Class T fuses are recommended below. Also allowed are UL Listed 248-8 Class J fast
acting, time delay, and high speed fuses, 248-4 Class CC fast acting fuses and 248-17
Class CF fast acting and time delay fuses of the same nominal voltage and current
rating.
Refer to notes below the tables.

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.
