Its interrupting capacity hits 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V — so it handles high-fault scenarios downstream of a transformer or generator feed without cascading upstream.
Above that it derates: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C.
Maximum power loss is 96 W at rated load; factor that into your enclosure thermal budget if the panel is sealed or tightly packed.
