Its TM240 thermal-magnetic overcurrent release is fixed — no field-swap trip units here, so the rating on the nameplate is the rating you commit to the BOM. Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V, which covers most industrial distribution panels and motor control centers without needing an upstream current-limiting fuse.
The 160 A rating holds flat from 40 °C up to 50 °C, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
