The only problems I know of related to the TPU are software bugs and I believe these problems have been addressed in v4. If you're relay tripped on the differential element for a fault outside the zone of protection then I would re-evaluate your CTs.

Make sure that they are properly matched, they are of sufficient accuracy class to supply the burden, and will provide appropriate saturation to prevent nuisance trips. If you have waveform capture set up in your TPU then you should be able to look at the oscillography and compare the CT contributions to the relay during the fault. If the relay tripped on an overcurrent element then you may need to re-evaluate your protective device coordination.

The relay may have been set to operate too quickly causing the overtrip. If everything checks out then the downstream control circuit and relay may have failed to operate properly to open the breaker. I'd be interested in hearing what you find out. Please post the result. I have one TPUR in service and have had no problems We've had some pretty nasty thru faults too. There was a firmware upgrade a year or so ago that ABB was very anxious to install on a relay that one of our clients had in service.

ABB came out and did the upgrade while the relay was in service. I would check your firmware version with ABB just to be sure. I don't know the nature of the problem. Four years in service at a client's plant, no real problems. There was a case of tripping on through fault these are quite frequent on this system - turned out to be harmonic restraint setting problem.

I managed to reproduce the fault from the recording on a Pulsar test set and proved the corrective action, which was a setting adjustment. No recurrence after correction.
