摘要： A circuit breaker includes a first lug and second and third acoustic lugs electrically connected to a power circuit. Separable contacts are electrically connected in series between the first lug and the second acoustic lug. An operating mechanism opens and closes the separable contacts. A first acoustic sensor is coupled to the second acoustic lug and senses a first acoustic signal from the second acoustic lug. A second acoustic sensor is coupled to the third acoustic lug and senses a second acoustic signal from the third acoustic lug. The first and second acoustic signals are operatively associated with a power circuit fault. A current sensor senses a current flowing between the first and second lugs. A circuit inputs the sensed acoustic signals and the sensed current and detects and distinguishes a parallel arc fault or a series arc fault from the sensed acoustic signals and the sensed current.
