Once a power system is established it is necessary to protect it from faults (whether internal or external). The authors use some protecting and sensing device like circuit breakers, relays, fuses etc. Circuit breaker is a mechanical device capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time. This paper represents information about the basic types and electrical characteristics of circuit breaker based on medium used for arc quenching, that how it automatically breaks currents under specified abnormal circuit conditions such as those of faults.
