The Siemens SENTRON 3VA2340-7HL32-0DA0 is a 3-pole molded case circuit breaker rated for 400 A continuous current at 40 °C through 50 °C, with a slight thermal derating curve down to 340 A at 70 °C. Its interrupting capacity hits 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V — meaning it can handle high-fault utility feeds or transformer secondaries without cascading upstream. This is a line-protection design (not a motor-protective breaker), so it's intended for feeder and distribution panels where you need selectivity and high short-circuit withstand.
