Guess you're from the UK? I think it's one of the only places in the world that does that.
No, usually not, though better power strips will have one. But you don't need to go over the specified amps to cause a fire, there are multiple places that could overheat - extension cable, connections, solder points - while still being under the fuse rating if this thing is running at max power for a long time. The main job of a fuse is to protect against power surges / short circuits.
