Gidday Randy!,
Well, that is a new development.
Do you have to replace the whole unit if the surge suppressor "blows"?
You can get surge socket outlets here that have a little plug-in module in them and you just replace the module should it blow.
I would imagine that this sort of thing would have a device like an MOV (Metal Oxide Varistor) in it as the suppressor.
One final thing, it doesn't mention what the actual clamping voltage of the suppressor actually is.
