FIELD: electrical engineering.
SUBSTANCE: present invention relates to two-functional circuit breakers or arc fault breakers. Linear and neutral conductors for a circuit breaker defining arc fault, for example, a miniature circuit breaker, are made as a rigid conductor surrounding and retaining an isolated flexible conductor, passing through a current transformer of an earth fault protection breaker. The measurement of voltage is carried out in parallel to the rigid conductor to detect arc faults and ground faults in the miniature circuit breaker in the space of a single current transformer.
EFFECT: elimination of a load shift error due to elimination of need for a twisted wire node.
