ABB 1SDA068103R1 is a 4-pole distribution breaker from the XT4N family, rated 160 A continuous (In) and 160 A uninterrupted current (Iu). The TMA thermal-magnetic trip unit is factory set to 50% of the maximum threshold, meaning it trips at 160 A on the thermal element.
Rated current In is 160 A; uninterrupted current Iu is also 160 A.
Physically yes — same XT4 frame, same dimensions and weight. However the trip rating is different (200 A vs 160 A), so the overcurrent protection setting changes. If the application requires 160 A, this is the correct part; the 200 A unit can only be used if the system coordination permits a higher setting or if the trip unit is field-adjusted.
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.
