Factory Promotional Electrical Switch Cabinet - TZN63A（TVS1）-24 Indoor high voltage vacuum circuit breaker – TENPRO Detail:
Scope of application
TZN63A (TVS1) -24 series handcart type indoor vacuum circuit breaker is indoor high-voltage switchgear with rated voltage 24kV, three-phase AC 50Hz. It is suitable for power plants, substations and industrial and mining enterprises and other transmission and distribution system control or protection switch, especially suitable for high altitude area breaking important load and frequent operation places.
The manufacture of circuit breaker accords with the national standard of GB1984-2003 AC High Voltage Circuit Breaker, DLT403-2000 3.6-40.5KV Indoor Vacuum Circuit Breaker Ordering Technical Condition, and relevant IEC standard, and has reliable interlocking function.
The operating mechanism of circuit breaker is spring energy storage type, and it can be operated by AC, DC energy storage, or manual manipulation.
The circuit breaker can be equipped with permanent magnetic actuator with long life. The mechanical life can be up to 60, 000 times, so that it can be used in the field of extremely frequent operation.
The circuit breaker is designed as the structure of front and rear mounting, which can be used either as a fixed installation unit or as a central unit fitted with a chassis car.
