Its breaking capacity reaches 242 kA at 240 V and holds at 187 kA through 440 V, then drops to 121 kA at 500 V and 4.5 kA at 690 V — so the voltage class of your system determines which fault level this breaker can clear. The 250 A frame carries a thermal derating curve: full rating up to 50 °C, then 238 A at 55 °C, stepping down to 200 A at 70 °C. That matters when the breaker shares an enclosure with other heat sources.
Built-in release and communication
Maximum power loss is 48 W, which should be factored into enclosure thermal calculations.
