SENTRON 3VA1340-6EE32-0AA0 — 400 A MCCB, TM220 Release
The Siemens 3VA1340-6EE32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 400 A at 40 °C ambient, derating to 367 A at 70 °C. Short-circuit breaking capacity reaches 220 kA at 240 V, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V — covering most industrial panel SCCR requirements up to 690 V.
Thermal Derating & Ambient Considerations
Above that, derate linearly: 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C.
Physical Fit & Panel Integration
Dimensions: 248 mm height, 138 mm width, 110 mm depth. The 3-pole footprint is standard for SENTRON 3VA MCCBs in this frame size. No communication module, undervoltage release, or ground-fault monitoring is built in — it is a basic line-protection breaker with a TM220 release.
