The interrupting capacity is the headline: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a 480 V panel (common in North American industrial), the 52.5 kA at 440 V is the closest published point — that's well above typical 18–25 kA available fault currents at a distribution panelboard, so you've got SCCR headroom for most downstream coordination studies. The 690 V figure (11.9 kA) is what matters if you're feeding a 600 V class motor control center. That keeps the part simple and broadly interchangeable, but it also means you cannot field-upgrade to a communicating breaker. If your spec calls for power monitoring or remote status, this is not the variant. That's a standard SENTRON 3VA1 frame size — it occupies the same panel footprint as other 3VA1 three-pole breakers in the 40 A range. Mounting is via the rear DIN rail clip or screw-mount adapter (not included); the IP40 front is rated for finger-safe operation inside a locked panel. If your maintenance team relies on a visual flag, factor that into the panel labeling.","metaTitle":"Siemens 3VA1140-4EF36-0HA0 SENTRON MCCB, 40 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1140-4EF36-0HA0 molded case circuit breaker, 40 A rated, 3-pole, TM240 release, 121 kA at 240 V.
