The present invention relates to an arc contact of a circuit breaker. The arc contact of the circuit breaker used in a gas insulated switchgear includes a finger support which includes a groove on an outer circumference side with a cylindrical shape, an arc contact member which includes a protrusion which is fitted to the groove and inwardly protrudes, and surrounds the finger support, a coupling which separately surrounds the arc contact member, and a leaf spring which is fitted into a separated space between the arc contact member and the coupling. The arc contact of the circuit breaker according to the present invention increases a contact rate between contacts by applying a division structure to the arc contact member and improves breaking performance. |
