Obviously you do not have the EE understanding required. A 220V surge protector is typically designed to clamp at around 500V. From rectified 110V AC that gives you a 350V relative spike into the capacitors. From rectified 220V it is only 190V. A 110V surge protector is typically designed to clamp at around 330V. That is an 180V spike. If you cannot see that a 350V spike may be a bit more destructive than an 190V/180V one, and that in particular, the components in the device may only be dimensioned for a 200V spike or so as that is what to expect with surge protection done correctly, then you have no business being in this discussion. If you have to ask where these numbers come from, the same applies.
Incidentally, this is only one of the problems with a wrongly dimensioned surge protector. And yes, the surge voltage is relevant, as it influences dU/dt and the surge current. In actual fact, there is a surge model behind this and the surge voltage is only one factor. Also, surge protection devices do not do a perfect clamping, and have maximum ratings. If they are exceeded, the surge protector may short out, fail or even start to burn if not fitted with a thermal fuse. Incidentally, there is a maximum of surges a surge protector can clamp, depending on the surges and its ratings. After that, it needs replacement.
Why do incompetent morons always feel they are qualified to comment on advanced engineering they really do not understand? The Dunning-Kruger effect is strong on Slashdot.
