The Siemens 3VA5340-6EF31-0AA0 is built for exactly that kind of job. It’s a 400 amp, 3-pole circuit breaker designed to handle the demands of commercial and industrial systems without overcomplicating things. This model sits in Siemens’ 3VA5 line, which a lot of contractors and facility teams stick with for one reason—it works, and it keeps working. With a 65kA interrupting rating at 480V, it’s ready to clear high fault currents quickly before they turn into bigger (and more expensive) problems. One thing people like about this breaker is the adjustability. You’re not locked into a single setting. The thermal magnetic trip unit (TM240) lets you dial in overload protection anywhere from 320A up to 400A, and set instantaneous trips between 5x and 10x. That gives you a bit more control when you’re trying to coordinate protection across a system. It’s a solid choice whether you’re replacing an existing unit or putting together a new panel. No fluff—just a breaker that does what it’s supposed to do.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRated 400 Amps: for mid-to-heavy electrical loads\u003c\/li\u003e\n\u003cli\u003e65kA @ 480V interrupting capacity: for high fault protection\u003c\/li\u003e\n\u003cli\u003e3-pole design: for three-phase systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit (TM240): for dependable operation\u003c\/li\u003e\n\u003cli\u003eAdjustable overload range: 320A – 400A\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip setting: 5x – 10x\u003c\/li\u003e\n\u003cli\u003ePart of the trusted Siemens 3VA5 series\u003c\/li\u003e\n\u003cli\u003eCompact size: makes panel installation easier\u003c\/li\u003e\n\u003cli\u003eLugs not included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siemens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3VA5340-6EF31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 65 kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e TM240 (Thermal Magnetic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Setting (Ir):\u003c\/strong\u003e 320A – 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Setting (Ii):\u003c\/strong\u003e 5x – 10x\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 9.8 in\u003c\/li\u003e\n\u003cli\u003eWidth: 6.3 in\u003c\/li\u003e\n\u003cli\u003eDepth: 5.9 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUL Listed: for use in U.S. electrical systems\u003c\/li\u003e\n\u003cli\u003eBuilt to Siemens manufacturing standards: for consistency and safety\u003c\/li\u003e\n\u003cli\u003eSuitable for installations requiring NEC compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYou’ll typically see this breaker used in:\u003c\/li\u003e\n\u003cli\u003eCommercial buildings and office spaces\u003c\/li\u003e\n\u003cli\u003eIndustrial facilities and production floors\u003c\/li\u003e\n\u003cli\u003eMain and sub distribution panels\u003c\/li\u003e\n\u003cli\u003eEquipment protection where higher fault current is present\u003c\/li\u003e\n\u003cli\u003eRetrofit projects where reliability matters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
