Using the CT-HSC-050-U with Arduino

Sensor Specs:

purpose of project: power measurement in a 3-phase power system

Question: Can these sensors be used with Arduino? The 0-333mV AC output seems like I would need to use an OpAmp to bring it into an acceptable voltage input range. Also, to test these, how would I wire them? Do I even need to resist them?

Thanks for any help.
