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.","metaTitle":"Siemens 3VA2340-5HN32-0AA0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-5HN32-0AA0 molded case circuit breaker, 400 A rated, 3-pole, ETU350 release, 187 kA at 240 V.
