Current Overload Switch

Nice.

Very cool circuit

wow! I'm impressed! it's very cool!

Very cool! 100 times better than a fuse

Overall voltage protection circuit!

The problem, i think, is that real bjt hasn't a fixed Vbe voltange so it's difficult to choose the bias resistance

good

Nice!

Will this fit into an inverter circuit, and should i build this into the dc side or ac section?

1) What do you mean, "will this fit into an inverter circuit?" Do you have an inverter already? If so, does the housing have room to fit these extra components? (You can squeeze these into a rather small PCB.) If not, are you then planning to build your own? If that's the case, then just design room for it accordingly. The other option is to simply put this circuit into its own enclosure, such as a small project box. Then drill four holes in it; one for a power in jack, one for a power out jack, one for a switch, and one for the LED. 2) If you can't tell that this is a DC circuit, I strongly suggest that you not try to build it and/or incorporate it into a pre-existing inverter. Study some more basic stuff first.

Nice

Lol = Lenz on lsd

Fools such as hurz are individuals who have disengaged their reasoning skills or simply don't have any, fortunately this problem is restricted to a minority. Snide remarks, contentious comments and demeaning statements are all symptomatic of the lack of reasoning skills. Knowledge in the absence of reasoning skills is moot, anyway, given their reluctance to reason with anyone who opposes their ideology, they have ostracised themselves from the rest of the community who posses reasoning skills. Cheerleading anyone who cannot reason with anyone who opposes their views is detestable.

And faceblast, if the shoe fits, wear it...
