Breaking capacity hits 187 kA at 240 V, tapering to 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries without cascading upstream.
Full 250 A rating holds up to 50 °C ambient; above that it derates linearly — 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. In a cement plant control room that sits at 55 °C near the kiln, you lose about 9 A off the nameplate.
