Its interrupting capacity hits 187 kA at 240 V, tapering to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V — so the high-fault performance lives at the lower voltages common in North American 240/480 V distribution, while the 690 V figure still clears a respectable fault for European 690 V industrial grids. The 250 A rating holds steady up to 50 °C, then derates to 241 A at 55 °C and 213 A at 70 °C, which means you don't lose headroom until the panel ambient climbs above 50 °C — useful in a hot MCC room or near process heat.
