4.6 Protective measures
The drive controllers are only suitable for operation on TN networks and only
for use in supply current networks that are able to provide a maximally
symmetrical nominal short circuit current at 480 volts according to the following
table.
4.6.1 Line fuse
The mains fuse ensures line and power protection in the drive controller.
You can use the following protective devices:
• Full range safety melt fuses for cable and circuit protection to IEC 60269-
2-1/DIN VDE 0636, part 201 NH fuses (operating class gG in accordance
with IEC operating class specification or slow blow in accordance with
VDE)
• Circuit breaker with trigger characteristics C in accordance with EN 60898
• Power circuit breaker
The following applies to size 3 (SD6A34, SD6A36, SD6A38): 
Operation only with mains commutation reactors and mains fuse for operating
class gG (see section "Line fuses" > "Full range safety melt fuses").
