Fuses (IEC)

Fuses protect the input cable in short-circuit situations. They also restrict drive damage
and prevent damage to adjoining equipment in case of a short-circuit inside the drive.
ABB recommends the high speed aR fuses specified below. The gG fuses can be used
for frames R3 and R6 if they operate rapidly enough (max. 0.1 seconds). The operating
time depends on the supply network impedance and the cross-sectional area and length
of the supply cable. Obey the local regulations.
