When an overload occurs the transistors immediately blow and short. Then a while later (1 or 2 seconds) the fuse blows.

Say, a fuse in the power supply is fixed at 10A. It will blow off (or trip) when the load (in our case, the system) starts to consume more than 10A!!(as a result of any short circuit or whatever!!)
Here on one side u r saying same as i am and u r agreeing to Mr Nigel
I cant understand!!!!
