Cicero:
I thin the Surge Stopper Devices

PTC's and even NTC's are very finicky to work with.
In a Fire Alarm panel I purchased each Class two output was protected with a PTC. You had a choice of PTC's or fuses.
Because of inrush currents some strobes would not operate., The manufacturer fixed the inrush problem in some devices, I had some of each. Class II supplies are around 100 W.
PTC's for motors work nicely because the overload characteristics are well known.
NTC;s were used in tube televisions. PTC's were used to run the degaussing coils.
In-rush current limiting and surge suppression are not quite the same and I had to use both. A Y-Delta motor starter is sort of a soft start.
