AC 230V over current & short circuit Protection.

Hi friends


In this Tutorial  i have made an AC 230V over current & short  circuit Protect.  You can use it with power supply or other device to limit the current. I have used very common components to make this circuit. Short circuit and high current protection circuit for AC 230V. If a PCB  is connected to AC 230V through fast Trip, the IGBT/MOSFET/capacitors etc in the PCB will not damage if there is an error in wiring/assembling. Fuse / MCB and other device cannot protect IGBT/MOSFET because these active components will fail before the fuse/MCB can protect it. So it is very important and powerful device.

      Connect the load and adjust the setting value of IC pin number 2 & 3 for over current and pin number 5 & 6 for short circuit. Finlay watch video show here. Thanks for stay with us.

      Ok thank you for the reply,. Now can you tell me please what CT you are using here so I can find datasheet of it so I know what output it has. Can I use it for 400 Volts 50 amps? Thank you again for the help
