Its interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V — so it handles high-fault utility feeds or transformer secondaries without cascading upstream. The continuous rating holds at 400 A through 50 °C, then derates to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C; that thermal curve matters if the breaker lives in a hot enclosure or next to other heat sources. The basic switch assembly is order code 3VA2340-7HL32-0AA0. A trip indicator is present, and the breaker includes no voltage-trigger or communication function — it's a straight line-protection device, not a power-monitoring unit. Maximum power loss is 98.5 W at rated load — factor that into enclosure ventilation if the panel is tight.
