In=2000? That must be checked from the rating plug (#12 on the instruction photo), NOT from the specs sticker. Though the frame is a 2000A, the trip unit can actually be downsized to 1600, 1250, 100, 800, 630(?)A by simply exchanging the rating plug. And that will directly affect the reference In for all settings. Regards, ABB Tech Support
@@amaan8670 pop out with a screwdriver (or 2, to go straight) and put a smaller one in. Cannot be replaced with bigger than sold, only smaller. However, L setting I1 can be as low as 40% of nominal current, so a lower rating plug is not that often needed. Typically only with smaller currents in high short-circuit or high temperature conditions.
Thank you so much it was very helpful
