Breaking capacity or interrupting rating is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.reaking capacity current corresponds to a voltage, so an electrical apparatus may have more than one breaking capacity current, according to the voltage.
Circuit Breakers. A circuit breaker is a switch that automatically interrupts electrical flow in a circuit in case of an overload or short.Homes built or rewired since the mid-1960s use circuit breakers to monitor the electricity coming into the home.
