12KV 630- 2000A VACUM VCB Circuiter Retirable Alta estabilidad
Voltage: | 12-24KV | Current: | 630-2000A |
Breaking Current: | 25KA Max | Type: | Withdrawable |
Standard: | GB,ISO,IEC |
El interruptor del circuito de la serie VS1 presenta una alta estabilidad y alta confiabilidad
El "interruptor de circuito de vacío de alto voltaje" se nombra porque tanto el medio de extinción de arco como el medio aislante del espacio de contacto después de la extinción del arco son vacío; Ventajas, la aplicación en la red de distribución es más popular.
El disyuntor es identificado por algunos estándares nacionales y estándares relativos internacionales, como GB1984, GB/T11022, DL/T403 e IEC62271, etc.
