Inside a 13,500A surge protector. (With schematic.)

This surge protector wasn't very expensive, but is actually very well made. It would be worth using one plugged into a spare empty socket to provide a level of transient voltage spike suppression for other items in your home.
This one came from CPC in the UK (Farnell / element14)

The brand Brennenstuhl have a bit of a mixed history of electrical devices, including fluorescent striplights that used a DC multiplier to strike and run the tube - cheap, but very short lamp life. But their stuff is generally OK.
With the proper thermal protection for the MOVs (if the thermal fuses are good quality) and clean layout inside, this suppressor adaptor looks absolutely fine. It went back together easily and I'll be using it as a layer of extra protection against mains borne voltage spikes here.
