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").
UL-compliant line fuse
Use the following fuses for UL-compliant operation:
•
Fuses of class RK1, for example Bussmann KTS-R-xxA/600 V.
•
For drive controllers sizes and 1 you can also use fuses of class CC.
•
For drive controllers size 0 to 2 you can also use type E motor starters from
Eaton Industries, consisting of a motor protection switch and supply
terminal.
