The 1SDA068097R1: This is an ABB XT4N 160 fixed thermal-magnetic breaker set to 40 A. The frame is rated for 160 A, meaning the trip unit can be swapped up to that limit if the load grows — same panel cutout, same terminals. That's useful when you're planning for future expansion and don't want to re-pull wires. Rated for 690 V, 4-pole, 50/60 Hz. Drops into any standard XT4 panel footprint. No surprises on the swap.
The In is 40 A, with a frame rating (Iu) of 160 A.
