Breaking capacity hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V, so it handles high-fault utility feeds and transformer secondaries without cascading upstream.
At 500 V and 690 V the interrupting rating holds at 11.9 kA — still enough for most 480V/600V industrial distribution panels, but you'll want to verify coordination with downstream breakers if the available fault current is above that.
At 60 °C and 65 °C it drops to 19 A; at 70 °C it stays at 19 A. That's a shallow derating curve, so you can push ambient without oversizing the frame.
