Issue:
Using Class T fuses with Altivar 31 drives

Product Line:
Altivar Drives

Environment:
Altivar 31 drives

Cause:
Selecting fuses for the ATV31

Resolution:

The ATV31 units were tested with the Class J fuses however the 600V version of the Class T fuses have equivalent ratings. So can use the 600V Class T fuses but not the 300V Class T fuses.
