3AV5 circuit breaker series is indoor high-voltage switchgear, suitable for rated voltage 12 kV, frequency 50 Hz three-phase power system, as protection and control appliances, with high reliability, easy operation, simple maintenance and other characteristics. The circuit breaker can be used for middle-type switchgear and fixed switchgear as well as oil-free transformation. Because of the special advantages of vacuum circuit breaker, it is especially suitable for frequent operation requiring rated current, or many times to break the short-circuit current. The 3AV5 vacuum circuit breaker has three installation modes: fixed type, extraction type and side mounted. For special requirements, please contact the manufacturer.
