It is an Overload and Short Circuit Protection System Project Circuit Diagram that protects your layout from short circuits and overloads. It is essential to prevent damage to equipment. There are many options available in the market like MCB, electronic circuit breakers, etc. But this project has some main features, in this project we can select the overload and short circuit current according to our load capacity, this circuit has a 7 Amp. relay but it is designed only for 0 to 2Amp (up to 400watt). We can easily upgrade the circuit capacity by changing the relay and CT rating.

Specifications & Features:-

• Easy to select the current range using presets for desired output.
