Its interrupting ratings hit 187 kA at 240 V and 121 kA at 415 V and 440 V, so it handles high-fault utility feeds without cascading upstream — the SCCR stays at 75.6 kA at 500 V and 4.5 kA at 690 V, which covers most industrial step-down transformer secondaries. Thermal derating is linear above 50 °C: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
