the ac circuit breaker is sub-classified into two types, i.e., the low voltage circuit breaker and the high voltage circuit breaker. the circuit breaker whose value lies below the 1000v is known as the low voltage circuit breaker, and above 1000v it is known as a high voltage circuit breaker.,chapter (2) circuit breakers,circuit breakers can be arbitrarily classified using criteria such as, 1. intended voltage application, 2. location of installation (i.e. outdoor, indoor), 3. their external design characteristics, or perhaps the most important, method and medium used for the current interruption. this is shown in fig. 5.
