Short circuit
SD700FL includes from frame 5 to 11 ultra fast fuses as standard. Frame 5 includes one fuse per
phase with a rated current that depends on the drive
‟s nominal current. Frames 6 on are
constructed through the parallel connection of frame 5 so the fuses per phase in those frames
correspond with the number of parallel drive modules (frame 5) interconnected. The breaking
capacity of the fuses and the rated current is described in the following table.
Therefore, it is not recommended to install the drive in points where the short-circuit current
available is higher than 200kA. If so, install general fuses with a greater breaking capacity and
with fastest overcurrent capacity.
Acquiring frames 1 to 4, the installer must select a protection according to the characteristics
mentioned previously.
