Circuit Project Electronic

If fuse slow get into trouble not good may make the circuit can is damaged. Normally fuse torn when current change too much. But more will torn must use the period of time which may late go to all right with regard to add SCR go to make fuse torn fast go up by when voltage exceed more at ZD fix. Make SCR work have current flow through very quickly. Make power supply and load safety. An example is if friends use load 5V as a result should use Zener Diode 5.6V sizes etc.
