ZN23-40.5 series indoor high voltage vacuum circuit breaker

Indoor high-voltage vacuum circuit breaker The indoor high-voltage vacuum circuit breaker is a three-phase AC, rated voltage for indoor installation, equipped with a spring operating mechanism. The products are divided into two types: fixed type and handcart type. The fixed type is a configuration type fixed high-voltage switch cabinet that uses a handcart type configuration and is used in an open metal-enclosed switch cabinet or a high-voltage switch cabinet on the vehicle. It can also be configured and used in an on-board metal-enclosed switch cabinet on the vehicle. The technical parameters of this series of products are high breaking capacity, strong action, reliable performance, stable performance, long life, easy maintenance, and no explosion hazard or pollution. They are used for industrial and mining enterprises, power plants and substation control. They are also suitable for places with frequent operations and can also be used to meet specific needs. Capacitor banks and other special occasions.
The vacuum circuit breaker is rated voltage. , three-phase AC indoor high-voltage electrical equipment, suitable for control and protection switches in power transmission and distribution systems such as transformer stations in industrial and mining enterprises. It is especially suitable for metallurgy, electric arc furnaces and other places that require frequent operations as control and protection equipment.
This product complies with the "AC High Voltage Circuit Breaking" standard. The circuit breaker handcart can be directly pushed into the cabinet and can be installed and used independently without removing the plug.
