    Don't think its a surge suppressor as there was no ground leg. Most surge suppressors I have seen also have a light that says it still working.

    I was thinking some type of noise filter...

    When things like this comes up, why not call the manufacturer? Square
    D has a factory in Lexington, KY. I bet a dollar to a donut that with a phone call Square D will tell you exactly what it is and if it is installed correctly.

    Surge suppressors do no need a ground, they simply need the two hot phase legs and the neutral leg, the surge will got to neutral (which is, by the way 'ground').

    Why bother, we have already told you that here.

    It is a surge suppressor and it is not installed correctly.
