Its TM220 thermal-magnetic trip unit gives you an overload Ir adjustable from 18 A to 25 A and a fixed short-circuit pickup at 12.8 × In (320 A at the 25 A setting). The interrupting capacity hits 25 kA at 415 V — that's the N (normal) breaking class, good for most distribution panels that aren't feeding a high-fault transformer. The N conductor is left unprotected on this variant; the nut keeper kit keeps the lug hardware from walking loose under vibration in a panel or enclosure.
