Low. The entire vehicle is made from 15-30mm plates (absolute plate thickness, not LOS), with only parts of the turret having space for composite armor – which was never installed. Unknown if weights were added inside to compensate for that during trials, or if it went lighter than it should.
Hull is pure steel/bimetal plates at most. The composites were said to stop 105mm heat and darts from the time (probably meaning old short darts), and there were talks of trying to enhance it so the final layout could stop 120mm darts. I don’t know if it ever came to this result, my guess would be: no.
Edit: it’s something like this, don’t expect Leo2/M1 levels of armor at all. It’s kind of a re-skinned, less mobile AMX40. Gun mantlet probably closer to green than blue as well.
