Victron VM-3P75CT alternative CT for UK meter tails

Does anybody know what the effect on one of these is if you take it over 80 amps? Is it going to damage it or will it just loose some accuracy? You can get the CTs round UK meter tails if you strip back the outer insulation of the double insulation (inside an enclosure!) but I do sometime take my connection up close to the 100 amp max.
