It carries a 220 kA interrupting capacity at 240 V, stepping down to 154 kA at 415 V and 440 V, and 17 kA at 690 V — the SCCR headroom needed for high-fault utility feeds or transformer secondaries where a standard MCCB would cascade-fail upstream. Above that, derating is linear: 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C. For a panel OEM stuffing a 400 A feed, the 50 °C ceiling means no ampacity penalty in a ventilated enclosure; above that, the derating curve governs the actual load you can hang on the line. ## Breaking capacity by voltage The interrupting ratings span the voltage range a site electrical engineer needs for selective coordination studies: 220 kA at 240 V, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V. At 690 V the 17 kA rating is lower but still adequate for most 690 V motor control centers with current-limiting fuses upstream. ## Physical integration and environment Maximum power loss is 92.1 W, which factors into enclosure thermal calculations for a multi-breaker lineup. ## Release and protection design The breaker is configured for line protection (not ground-fault or N-conductor protection), and the short-circuit protection design references the 3VA device manual for DC switching applications.","metaTitle":"Siemens 3VA1340-6EE42-0AA0 SENTRON MCCB, 400 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1340-6EE42-0AA0 molded case circuit breaker, 400 A continuous, 4-pole, 220 kA interrupting at 240 V.
