I might be wrong, but it looks to me like this circuit best provides a voltage boost. I guess there is one choice for voltage reduction. So, it might not be a good choice for handling an over-voltage situation from the mains supply.
>> It depends on how you sense the voltage at the input, is it HIGH or LOW,
I will come with another circuit which might be meaningful.
I don't understand what you mean by "cut off" situation. What is "cut off"?
>>I do mean at low and high voltage compared to 220VAC( few % fluctuations) the load will be diss-connected from the system or it will be "on-hold" for a period.
