Yes, not enough information supplied in that product description to know everything required to wire to an arduino. This much is clear from the description, it's a straight AC only CT (current transformer) that requires a fixed resistor across the it's output connections to develop a AC voltage proportional to the AC current flowing in the primary of the CT. The size of the resistor is unknown because they fail to give the turns ratio of the CT. Once the resistor size is calculated correctly and installed, then you need to rectify and filter the AC and possible scale the voltage so that AC current range is converted to DC voltage range of no more then 0-5vdc to represent 0 to max amps of the primary current flow. So find a real datasheet before proceeding. Operating the CT with out a output load resistor on the CT output pins can destroy the CT and subject you to very high voltages due to the normal very high turns ratio that CTs use.
