CONTACTOR ASSEMBLY FOR CURRENT LIMITABLE CIRCUIT BREAKER

摘要

PURPOSE: A contactor assembly of a current-limiting type molded-case circuit breaker is provided to limit an accident current by blocking an arc generated from connection and separation of a movable contact and a fixed contact. CONSTITUTION: A molded-case circuit breaker includes a fixed contact(110) and a contact unit. The movable contact includes a first movable contact(210) and a second movable contact(220). The first and second movable contact rotates individually. The first moving contact(211) is formed in both ends of the first movable contact. The second moving contact(221) is formed in both ends of the second movable contact. The spacer member is arranged between the first and the second movable contact in order to keep an insulating state between the first and the second movable contact.
