Return to ProjectsElectronic Fuse for DC Short Circuit Protection by BRX46
Posted Jan 13, 2012 at 1:47 pm
Project Summary
This is an electronic fuse that protects the load against short circuit.
Project Description
Figure 1
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.

4 years ago: plaise i want schematic circuit for circuit electronic
4 years ago: plaise i want schematic circuit for circuit electronic fuse lm 3915 and lm3914
2 years ago: I'd be better careful in choosing the components that I will use especially the relays , cheers!
2 years ago: 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
10 months ago: the circuit of fuse(electronic fuse and temperature controler is best crciut electronic for protetion the cite and protege the wold i like eletronic is the best job for me,
