Breaking capacity is 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 240 V that's a very high interrupt rating — suitable for large transformer-fed or generator-fed fault currents where standard 65 kA or 100 kA MCCBs would need upstream fusing. ## Integration and Physical Fit That 110 mm depth is standard for this frame size — fits most 400 A MCCB panel cutouts and busbar arrangements without a deep enclosure. The 138 mm width means it occupies three pole spaces on a DIN-rail or panel-mount base. Rated insulation voltage 800 V. ## Auxiliary and Accessory Provisions Comes with 1 auxiliary switch + 1 trip alarm switch HQ. Trip indicator is present. If you need shunt trip, UVR, or comms, this base variant doesn't carry them — you'd add external accessories or step to a different order code. The supplied basic switch is 3VA13406EF320AA0.","metaTitle":"Siemens 3VA1340-6EF32-0AF0 SENTRON MCCB, 400 A, 220 kA","metaDescription":"Siemens SENTRON 3VA1340-6EF32-0AF0 molded case circuit breaker, 400 A rated current, 220 kA breaking capacity at 240 V. 3-pole, line protection, TM240 release.
