Its headline rating is 1000 A at 40 °C, which holds steady through 50 °C — only then does it begin a gentle derating curve: 960 A at 55 °C, 940 A at 60 °C, 920 A at 65 °C, and 900 A at 70 °C. That means in a 40 °C panel you get the full 1000 A; push the ambient to 70 °C and you still have 900 A available, which is useful headroom for a warm enclosure. The breaking capacity is what decides if this breaker clears a fault without upstream damage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V. No 'sold separately' fine print — the kit is complete for remote status and trip indication.
