Max zs of trimmed mccb
Good morning, I have had a quick read through but can not find and information relating to max zs. My question is if I used for example a 100A to 160A trimmable mccb but set it to 120A, is the max zs the 160A rating or 120A ? I am under the assumption ok it is set but someone could potentially turn it up?( worse case scenario)
