That 400 A holds flat through 50 °C — no derating needed until you cross 55 °C, where it steps to 375 A, then 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Interrupting capacity is the headline number here: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That SCCR covers most industrial service-entrance and distribution applications without cascading upstream — you can coordinate downstream breakers against this fault rating. The ETU550 is a communicating electronic trip unit — this breaker carries a communication function, so it can talk to a BMS or SCADA via the SENTRON communication modules. No undervoltage release or shunt trip fitted from the factory, and no ground-fault monitoring version. If you need those, they're accessory-add options on the 3VA platform.","metaTitle":"Siemens SENTRON 3VA2340-8JP32-0AA0 MCCB, 400 A, ETU550","metaDescription":"Siemens SENTRON 3VA2340-8JP32-0AA0 molded case circuit breaker, 400 A continuous, ETU550 electronic trip, 440 kA at 240 V.

The 3VA2340 is a larger-frame breaker (400 A continuous) compared to the 3VA2040 series which tops out at lower currents.
