The interrupting ratings are where this breaker earns its keep: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. This breaker measures 70 mm deep, 101.6 mm wide, and 130 mm tall — a standard SENTRON 3VA frame size that drops into the same DIN-rail or panel-mount footprint as other 3VA breakers. At 10.8 W maximum power loss, heat dissipation is modest; you won't need forced ventilation in a typical 600 mm x 800 mm enclosure, but it's worth accounting for if you're packing several breakers side by side. If you need those accessories, you're looking at a different suffix in the 3VA family.","metaTitle":"Siemens SENTRON 3VA1140-6ED46-0AA0 MCCB, 4P, 40A, 220 kA at","metaDescription":"Siemens SENTRON 3VA1140-6ED46-0AA0 molded case circuit breaker, 4-pole, 40 A rated, 220 kA interrupting at 240 V.

The 3VA1140-6ED46-0AA0 is a 4-pole, 40 A frame with the high-interrupt TM210 release. They share the same mounting footprint and terminal spacing, so one can replace the other in the same panel if the circuit design allows for the pole count and rating difference — but verify the interrupting requirements and neutral switching before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1140-6ED46-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1140-6ED46-0AA0 when reusing this data.
