Breaking capacity runs 440 kA at 240 V, 330 kA at 415 V, and 52.5 kA at 690 V, so it handles high-fault utility feeds and transformer secondaries without cascading upstream. Full 400 A rating holds through 50 °C. Above that it steps down: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C. Maximum power loss is 96 W at rated load; that heat has to leave the enclosure. ## Integration notes The auxiliary switch configuration is 2 aux + 1 trip alarm switch (HP type). Storage range -40 to 80 °C; operating -25 to 70 °C.","metaTitle":"Siemens 3VA2340-8HL32-0AJ0 SENTRON MCCB, 400A, 3-Pole, ETU32","metaDescription":"Siemens 3VA2340-8HL32-0AJ0 SENTRON molded case circuit breaker, 400A at 40°C, 3-pole, ETU320 electronic trip unit.
