Hi Davidbeach
Thanks for your answer. So basically FVNR starter can't rotate a motor in reverse direction where as FVR (two contactors) can change the motor direction. Is it right?
Does Fuse TCC depends on system voltage?
i.e. is it possible to have diff. Time current characteristic (curve) for a fuse if used at different system voltages (like 2.4kV or 5.5kV)?
