sfu is called as switch fuse unit.this will be used to
switch on/off a motor or vfd's etc.According to the current
rating of the motor i.e calulated by p=1.732 vi cos0 fuse
rating will be three times of that motor current and the
fuse rating will decide the sfu rating.if fuse is 64A in all
three phases then the sfu will be 64A.
