Abstract:
The current Circuit breakers have a fixed current rating from the manufacturer and whoever buys it must evaluate the current rating of the loads. However, it is inevitable to maintain the same loads for years. For every appreciable change in the load, another circuit breaker is needed to support the installed loads. This result into high cost of circuit breaker purchase and its installation, if the circuit breaker is not changed, it means undesired tripping. This paper aim to design an adjustable rated current circuit breaker based on Microcontroller which automates the reset of the adjusted current rating. If the set current is more than the current rating of the load, then the Circuit breaker does not trip and the load gets power after the refresh button pressed however, if it's below, the Circuit breaker trips instantly and its red LED goes off too.
