Minimum voltage rating of the protection device should be 250 Vac for 240/120 Vac and
240/200 Vac rated drives, and 600 Vac for 480/400 Vac and 590/480 Vac drives.
Current limiting type fuses should be used when input fusing is required. Select fuses with
low I 2 T values, rated at 200,000 AIC. Recommended fuses are Bussman type KTK-R.
Similar fuses with equivalent ratings by other manufacturers may also be acceptable.
