It's configured for line protection — no ground-fault monitoring, no phase-failure detection, no communication module.
Interrupting capacity — the real number for fault duty
The interrupting ratings span the voltage range you'll actually see in industrial distribution: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. On a 480 V or 400 V panel with high available fault current, those 121 kA numbers mean this breaker can clear a bolted fault without venting or welding contacts — it's sized for a main or large feeder position, not a branch tap.
Thermal derating and panel space
Above that it derates linearly: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. If your enclosure hits 60 °C inside, you're still good for 92.5 A — no need to oversize the frame. Power dissipation peaks at 13.5 W — negligible for thermal calculations in a ventilated enclosure.
