The ABB 1SDA068098R1 is an XT4N 160 TMA distribution circuit breaker with a fixed 50 A trip unit (In) inside a 160 A frame (Iu). This means the continuous load rating is 50 A, but the frame can accommodate trip units up to 160 A if swapped. For a panel builder, that headroom allows later uprating without changing the breaker base.
