7.3.2.2 Recommended Fuses for UL Compliance
•
The drive modules are supplied with built-in AC fuses. The modules have been qualied for 100 kA short circuit
current rating (SCCR) for the standard busbar congurations at all voltages (380–690 V AC).
•
The drive system is qualied for 100 kA SCCR with any Class L or Class T UL-listed fuses connected at the input
terminals of the drive modules, if no power options or extra busbars are connected externally.
•
The current rating of the Class L or Class T fuses should not exceed the listed fuse rating in Table 7.20 to Table 7.23.

7.3.4 Short Circuit Current Rating (SCCR)
The drive modules are supplied with built-in AC fuses. The modules have been qualied for 100 kA short circuit current
rating (SCCR) for the standard busbar congurations at all voltages (380–690 V AC). For more information on short-circuit
protection of the drive modules, see chapter 7.3.1 Protection. For more information on the recommended fuses for CE or UL
compliance, see chapter 7.3.2.1 Recommended Fuses for CE Compliance or chapter 7.3.2.2 Recommended Fuses for UL
Compliance, respectively.
