Interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so the SCCR headroom is substantial on lower-voltage secondary taps, but drops off sharply above 500 V. If you need those, you're looking at a different suffix.
Derating starts at 55 °C (154 A), then 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. Maximum power loss is 25.5 W. That's modest for a 160 A frame, but in a sealed, high-density panel, add it to your thermal budget.
If you're replacing just the trip unit or the switch body, those are the sub-components to cross-reference.
