The Incoming breaker model is Terasaki - S250-PE, 250 Ampere Frame rated for which Ics is 70kA, Category A breaker

The outgoing breakers model is Terasaki - H125 NJ, 125 Ampere Frame rated for which Ics is 85kA,Category A breakers

The bus bar rating is 65kA for 1s.

How should this panel board be specified, 65kA for 1s??. Since both the Incoming & outgoing breakers are of category A breakers, Is it correct to mention the time rating along with the short circuit?

Generally, How is the panel board short circuit is mentioned in the name plate of the board for which the Incoming & Outgoing breakers have different breaking capacity?
