The Siemens SENTRON 3VA2340-5HN32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 400 A at ambient temperatures up to 50 °C — above that it derates linearly to 340 A at 70 °C, which is the maximum operating temperature. The ETU350 electronic trip unit provides adjustable overload and short-circuit protection, and the breaker's interrupting capacity ranges from 187 kA at 240 V down to 7.5 kA at 690 V, so the voltage level of your distribution system directly governs whether this breaker clears a fault without upstream coordination issues. At 415 V the 121 kA rating covers most industrial low-voltage switchgear applications.
No communication module, no undervoltage release, and no ground-fault monitoring are built in; those functions would need external accessories.
