What is the rated stable current of the VS1 vacuum circuit breaker? We often see such a parameter on the nameplate of the vacuum circuit breaker, or this parameter is seen on the manual. So what is the rated stable current? What is its value?
The definition of VS1 Vacuum Router rated stable current: The maximum short -time current value determined by the VS1F vacuum switch mechanical strength. When the three -phase short -circuit impact current does not exceed this value, the switch will not be damaged due to the effect of electric power. It reflects the ability of the switch to resist electrical power. (The rated peak tolerance current) The stable current indicates the ability of the circuit breaker to withstand the short -circuit current electric power effect.

What is the value of VS1 vacuum circuit breaker rated stable current? When the VS1 vacuum circuit breaker, the rated current is 630A, the turnover current is 20ka, and when 25kA, its rated stable current peak is 63ka, the rated current is 1250A, and the turnover current is 31.5ka. , The rated current is 1250-4000A, and when the turnover current is 40KA, the rated thermal stabilization current is 100ka.
