Open one up and see. It's basically the same thing as used for 120V in USA,
except it obviously has to be able to handle the 230V (+/- 10V) standard in
Europe AND be able to handle being plugged in either way.

I was not saying the operative level was 170, only that the sinusoidal peak
of a nominal 120VAC is 170V. Add 10% or more as needed.

Of course. So the real level where the protector acts would be higher than
170V, such as the 330V figure I have read in a number of places.
