EasyPower doesn't include options for TVSS; in fact, the words "transient", "surge", or "suppressor" don't show up in the software help menus at all. Anybody here know how to model those in EasyPower?

How about modelling it as a bus?

Thank you. I reached out to an EasyPower engineer who handles training. This is what they said:
Transient Voltage Surge Suppressors (TVSS) primarily protect electrical systems from voltage surges and spikes by quickly clamping over voltages and diverting excess energy to the ground. They help prevent damage to electronic equipment and increase system reliability but do not directly affect arc fault detection or clearing mechanisms.

Yes, but they are being "helpfully unhelpful". If you want the AFIE or available short circuit current at the surge suppressor, then I would recommend modelling as a bus.
