What are the requirements for selecting a circuit breaker in a high voltage switchgear? According to the selection of the vacuum circuit breaker (VS1) in the high voltage cabinet (KYN28), is it based on the high voltage side current or the low voltage side current of the transformer, or what else, what is the difference between the selection of the switching capacity of the incoming line cabinet and the outlet cabinet?

The VS1-10KV high voltage switch has a minimum current rating of 630A and a breaking capacity of 20~25KA. The short-circuit capacity of the 2000KVA transformer is much smaller than the breaking capacity of the switch. Can be used 630-25KA.
