ACH580 Ultra-Low Harmonic Drives Installation, Operation and Maintenance Manual
Fuses
UL class T fuses for branch circuit protection per NEC are listed below. ABB
recommends fast acting class T or faster fuses for drives installed in North America.
Check on the fuse time-current curve to ensure the operating time of the fuse
is below 0.5 seconds for frames R3 and R6 and below 0.1 seconds for frame
R8. Comply with NFPA70 (NEC) and all local.
Note 1: See also
ACH580-31 Hardware Manual
Note 2: Fuses with higher current rating than the recommended ones must not be
used.
Note 3: Fuses from other manufacturers can be used if they meet the ratings and
the melting curve of the fuse does not exceed the melting curve of the fuse
mentioned in the table.
Note: The UL listed fuses in the table are the required branch circuit protection.
Fuses are to be provided as part of the installation.
• Fuses are not included in the purchased drive and must be provided by others.
• Fuses with higher current rating than specified must not be used.
• Fuses with lower current rating than specified may be used if they are of the same
class and voltage rating. It is the user's responsibility to verify that lower current
rated fuses are compliant with local regulations and appropriate for the
application.
• Drive fuses must be used to maintain the drive UL listing. Additional protection
can be used. Refer to local codes and regulations.
