Surge protectors contain a semiconductor device that in some ways is similar to a special kind of fuse which constantly monitors the incoming voltage for "spikes" of very high voltage which, if not suppressed, could "zap" or destroy the equipment it is protecting.
Computers, televisions - and similar expensive and/or very fragile consumer electronics equipment - is worth protecting from damage from high voltage spikes by using a surge protector.
If the incoming voltage exceeds the rated "highest allowed voltage" of the semiconductor device, it instantly reacts to "clamp" the voltage - doing which may or may not blow the surge protector's internal fuse - thus, protecting the end-user's equipment from permanent damage by the "high voltage spike".
