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.
