Three poles, electronic ETU350M trip unit with adjustable trip classes 10A, 10E, and 20E — that covers most standard motor start profiles from quick-start pumps to higher-inertia conveyors. ## Breaking capacity — the real number that matters for selectivity The 440 kA at 415 V is the headline, but the 187 kA at 690 V is what you care about if you're feeding a 690 V drive or transformer. That's a serious interrupting rating — it'll hold fault current through a high-capacity transformer secondary without cascading upstream. Footprint is 105 mm wide by 181 mm tall by 86 mm deep — standard 3-pole MCCB envelope for the SENTRON 3VA2 family. If you need those add-ons, you're looking at a different variant in the 3VA2 range. Lifecycle status is current — no end-of-life notice, no last-time-buy clock ticking. That means you can spec it into a BOM without worrying about a forced redesign next year.","metaTitle":"Siemens 3VA2140-0MN36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU35","metaDescription":"Siemens 3VA2140-0MN36-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 3-pole, ETU350M release, adjustable trip class 10A/10E/20E, 440 kA at 415 V.
