The 1SDA068086R1: The TMA trip unit gives thermal-magnetic protection with an adjustable range 80–800 A, but this unit ships with the 80 A rating fixed. The 160 A frame means the breaker's bus and housing can handle larger trip coils, so a future upgrade to a higher In is possible in the same panel cutout—just swap the trip unit.
Lifecycle stage is listed as current, meaning ABB still manufactures this part. Standard distributor lead time is 2–4 weeks.
