The ABB 1SDA068121R1 is a 3-pole motor protection circuit breaker from the XT4 frame, rated 200 A continuous and 690 VAC. It uses an MA trip unit (magnetic-only), intended for direct motor starting duty where overload protection is handled separately. The type string XT4N 250 MA 200 confirms the frame size 250 with a 200 A setting and adjustable magnetic trip threshold from 1000 to 2000 A.
Both share the same XT4 frame dimensions (8.25 × 10.5 × 16 cm), so the physical mounting is identical. However, the trip unit differs (MA vs Ekip I), so a direct swap without verifying protection coordination is not advised.
Alternative models and sibling configurations in the same ABB series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
