    .

    It is a surge protector.

    A common mode acting filter with a high, broad band attenuation ratio.
    A ZNR varistor surge serves as the overvoltage suppression component.
    The earthed capacitors are tested and approved as so-called
    class Y noise suppression capacitors.

    See page 7 of the document below.

    Regards
