Breaking capacity is the headline: 220 kA at 240 VAC, 154 kA at 415 VAC, 121 kA at 440 VAC, and 17 kA at 690 VAC. ## Fit and Integration That 70 mm depth is a standard MCCB dimension — it drops into most Siemens SENTRON panelboards and switchgear cubicles without a sub-panel spacer. The width matches the 3VA platform footprint, so existing busbar and lug kits transfer if you're swapping a 3VA1110 or 3VA1112 frame. Integrated auxiliary switch: one auxiliary contact plus one trip-alarm switch (HQ design). The trip indicator is built in — no add-on module needed to signal a fault condition to a PLC or annunciator. ## Environmental and Storage","metaTitle":"Siemens 3VA1140-6EF32-0AF0 SENTRON MCCB, 40 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1140-6EF32-0AF0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, 220 kA breaking capacity at 240 VAC.
