Most Multi boards have a mechanical over current circuit breaker incorporated in them, identified as a "red" button and should be no more that 10 Amps, over time they become unreliable as well.
The units I had (and there were two of them) were Kemo units, completely potted and good German Engineering too, (almost as good as Hungarian ones)
They were rated to over 2kW but still could not handle the inrush current of my 12" table saw and eventually failed. Being potted made them not able to be inspected or serviced. So when I set off to buy more they were no longer produced. (see the purple Tag on it) There was a whopping 16 Amp Job but it had a prohibitive price, so I ended up resorting to just manually switching on gear.
