Neither type is meant to be used on more than 250 volts.
Even though the new harmonized voltage permit supplies up to 253 volts
I suspect that they mean a NOMINAL 250 volts.
I must admit that I have used on a standard UK mains supply, switches marked "240 volts AC" Even when the the supply voltage was 245 volts at the time of installation.
