Nothing fancy—just a solid unit designed to handle overloads and short circuits the way it should. It comes with a thermal magnetic trip unit (TM240), which is what most people expect in this range. The overload setting can be adjusted from 320A up to 400A, so you’ve got some room to match it to your system. The instantaneous trip is also adjustable, set between 5 and 10 times the rated current. It’s rated at 100 kA at 480V AC, so it’s suitable for systems where higher fault current is a concern. Size-wise, it’s pretty typical for a 400A frame, so it should fit into most standard setups without much trouble. Lugs aren’t included, so you’ll need to account for that. If you just need a dependable 400A breaker without getting into anything overly complicated, this one gets the job done.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e400 amp rating\u003c\/li\u003e\n\u003cli\u003e3-pole breaker for three-phase systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit (TM240)\u003c\/li\u003e\n\u003cli\u003eAdjustable overload: 320A to 400A\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip: 5–10x\u003c\/li\u003e\n\u003cli\u003e100 kA rating at 480V AC\u003c\/li\u003e\n\u003cli\u003eStandard size for this frame\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\u003ePart Number:\u003c\/strong\u003e 3VA5340-7EF31-0AA0\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 400A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM240, ATAM)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Range (Ir):\u003c\/strong\u003e 320–400A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Range (Ii):\u003c\/strong\u003e 5–10x\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100 kA @ 480V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.8\" H × 6.3\" W × 5.9\" D\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\u003cbr\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\u003c\/li\u003e\n\u003cli\u003eMeets standard electrical safety requirements\u003c\/li\u003e\n\u003cli\u003eSuitable for commercial and industrial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eCommonly used in panelboards and switchboards in commercial buildings or industrial facilities.
