The frame rating Iu=160 A sets the physical limit for the current path, so the trip adjustment range up to 1250 A only applies if the frame can support it — practically, the adjustable range is limited by the Iu of 160 A, meaning the highest continuous current you can set is the In rating of 125 A, but the breaker can handle short-time overloads up to its breaking capacity. The XT4 frame (8.25 cm wide x 14 cm deep x 16 cm tall) is shared across several current ratings, so panel cutouts and busbar connections are consistent. If you're swapping in a panel originally designed for a higher-rated XT4 breaker like 1SDA068109R1 (200 A), the physical mounting is identical — no rewiring needed for the breaker position, though the protective settings must be verified against the load. Mounts in the XT4 footprint; the cutout measures 8.25 cm × 14 cm × 16 cm. The TMA trip unit is adjustable; verify the dial is set to 125 A.","metaTitle":"ABB 1SDA068107R1 XT4N 160 TMA, 125 A 4p Distribution Breaker","metaDescription":"ABB XT4N 160 TMA 125-1250 4p, In=125 A, Iu=160 A, rated 690 V, 50/60 Hz.
