Depends on brand and model. They'll either perform above rated expectations, run hot, or burn out. Quite often, all three, and in that order.

I am on same page as MDshunk posted it will be one of the three but how long the overload will last .,, most case with serious overload it will either overheat or burnout some will survie pretty good but the calberation may be off wonkers some.

and one warning with current transformer never open any connection when you have load on current transformer otherwise it will self destruction it.

I would worry less about a ct than i would worry about what its connect to.

I have a few setups that far exceed the ct ratings but we use a shorting relay to protect the controls until the motor has started.

Depending on its design, it will most likely saturate the core and the secondary current will no longer be in proportion to the primary.
