Abstract

Electronic Circuit Breaker project is developed for the users to operate an automatic circuit breaker.

It mainly consists of a key Load sensor, microcontroller, driver section and relay section.

The load sensor(Current transformer) senses the load. If the load is exceeded the particular limit, the load sensor sends signal to the microcontroller. The microcontroller analyses the signal and controls the relay through driver section.

The relay is used as an electromagnetic switch. The relay will cut the power supply of the circuit when the load is exceeded.

The microcontroller used is PIC 16F73. The microcontroller program is written in assembly language
