The ABB 1SDA068085R1 is an XT4N 160 TMA 63-630 A 3-pole distribution circuit breaker, rated 63 A continuous with a 160 A frame – meaning the breaker's physical bus and contacts are sized for up to 160 A, but it ships with a 63 A TMA trip unit. That combination gives you a higher interrupting capacity than a native 63 A frame, and leaves headroom if you later re-trip to a higher rating within the same XT4 family without swapping the entire breaker.
