The selection of breakers are of course based on load but there are also other factors. - Over load and time etc.

I will give some references for you to study.

But get hold of a professional if you want a proper job to be done / contact manufacturere he will select a proper one for your load condition.

Also give a proper title to your posts.

We are there to help each other so " hello...is any body help me please...?" is redundant.

I would have loved "Selection of Breaker" or something of that type.
