Electronic Fuse for DC Short Circuit Protection by BRX46

Schematic - Electronic Fuse for DC Short Circuit Protection

Description

This is an electronic fuse that protects the load against short circuit. Relays must be chosen with a voltage value equals to the input voltage. Don't omit using the 100uF capacitor with appropriate voltage value with respect to the input voltage. If you can't provide, you can use C106 instead of BRX46.

You can adjust the current with using 10K potentiometer. If you will use the fuse with very high currents, lower the 0R6 5W resistor value (ex. 0R47, 0R33, 0R22 or 0R1). Watt value of the resistor should be increased also. 

You can download ARES PCB layout file of the circuit from here .

I'd be better careful in choosing the components that I will use especially the relays , cheers!

I could not find any BRX46. I really want to try this because I already tired using C106 in my previous circuits. I want to know the performance difference of the two. Can anyone help me...thanks a lot
