The project is designed to shut down the power supply when it is overloaded. Conventional circuit breaker like MCB based is on thermal bimetal lever trip mechanism. It is very slow and the trip time is dependent upon the percentage of overload.

This project senses the current passing through a series element and the corresponding voltage drop is compared against the preset voltage proportional to the current by a level comparator to generate an output for the load to trip.

The concept of electronic circuit breaker came into focus realizing that conventional circuit breakers such as MCBs take longer time to trip. Therefore, for sensitive loads it is very important to activate the tripping mechanism at the shortest possible time, preferably instantaneously.

This project is demonstrates fast tripping mechanism as against the slow one like MCB. Electronic circuit breaker is based on the voltage drop across a series element proportional to the load current, typically a low value resistor.

This voltage is sensed and rectified to DC which is and then compared with a preset voltage by a level comparator to generate an output that drives a relay through a MOSFET to trip the load. The unit is extremely fast and overcomes the drawback of the thermal type. It uses a microcontroller from 8051 family.

Further the project can be enhanced by using a CT for galvanic isolation between mains and control circuit. Power electronic devices such as thyristors / IGBTs can be used for ultra fast operation compared to all the methods.

Q & A
Q:  What is the difference between Electronic circuit breaker and normal circuit breaker?
A:  Normal circuit breaker is dependent on thermal bimetal lever trip mechanism, whereas Electronic circuit breaker is formed using current sensing element and comparators
Q:  What is the role of microcontroller in this project?
A:  The microcontroller is programmed to display the circuit breaker conditions.
Q:  Will it auto return after fault (overload) clearance?
A:  No, one has to restart the device, as it would toggle between on and off till overload condition is cleared.
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.

I got to know about edgefx through internet. I was searching electronic projects in google then i got about edgefx website..
I have decided to buy project from edgefx because there was no time for me. So, i have decided to purchase project from edgefx. I like most about edgefx kit is complete kit.
the kit was delivered in time with right components.
the support team has helped me in purchasing the project.
Provide more and more advanced projects for upcoming students.
i already gave reference to my friend.

I got to know about edgefx through google. I was searching electronic projects in google.
I have decided to purchase project from edgefx because my project is similar to website project.. I like most about edgefx kit was cost is less.
i have call the number which is in the website.. So, in that way i got the help in purchasing the project.
the kit was delivered but little late with right components.
i would like to give reference to my juniors.

I come to know about Edgefx through Internet. I used embedded projects as a keyword in the Google.
I decided to buy a kit from Edgefx by having a look on the website it’s attractive. I like the complete kit.
I purchased through online.

I was searching Ultra Fast Acting Electronic Circuit Breaker and I find in the Google.
I found my project Title so decided to buy that project
I purchase through online
