Does the 9065 SSOLR provide under and over voltage protection?

Not as such. It provides phase loss/phase unbalance protection so if you had an under or over voltage condition on 1 phase, the SSOLR would see it as a phase unbalance and it would trip if the difference is 25% or greater. For true under or over voltage protection, use a voltage sensing relay.
