FIELD: electricity.
SUBSTANCE: invention relates to a circuit breaker unit of a power switch. Circuit breaker unit of a power switch with switch gap is located between first and second arcing contact elements (4, 5). Between both arcing contact elements (4, 5) there is switch gap (10). Switch gap is switching gas channel, which diverts switching gas to hole (24) for releasing switching gas in circuit breaker unit of power switch. Switching gas channel has first and second tubular sections (12, 13), which, at least partially overlap with each other and have in their side surfaces corresponding discharge holes. Free through discharge holes in first and second tubular sections (12, 13) are arranged with axial offset relative to each other.
EFFECT: higher efficiency of removing switching gas.
