To protect the drive system in case 1 or more internal
components break down within a drive module, use fuses
and/or circuit breakers at the mains supply side.
5.4.1.1 Branch Circuit Protection
To protect the installation against electrical and re
hazards, protect all branch circuits in an installation against
short circuit and overcurrent according to national and
international regulations.
5.4.1.2 Short-circuit Protection
Danfoss recommends the fuses listed in
chapter 5.4.1.3 Recommended Fuses for CE Compliance and
chapter 5.4.1.4 Recommended Fuses for UL Compliance to
achieve CE or UL Compliance in the protection of service
personnel and property against the consequences of
component breakdown in the drive modules.

5.4.1.4 Recommended Fuses for UL
Compliance
•
The drive modules are supplied with built-in AC
fuses. The modules have been qualied for
100 kA short-circuit current rating (SCCR) for the
standard busbar congurations at all voltages
(380–690 V AC).
•
If no power options or extra busbars are
connected externally, the drive system is qualied
for 100 kA SCCR with any Class L or Class T UL-
listed fuses connected at the input terminals of
the drive modules.
•
Do not exceed the listed fuse rating in Table 5.6
to Table 5.7 with the current rating of the Class L
or Class T fuses.
