It’s part of the 3VA5 line, so you’re getting a newer-generation design designed for everyday use in commercial and industrial setups. This one uses a thermal-magnetic trip unit (TM230). In plain terms, it handles overloads and short circuits the way you’d expect—nothing overly complicated, nothing you have to babysit. The overload protection is fixed at 350A, so what you see is what you get. For short-circuit protection, you’ve got an adjustable instantaneous trip (5–10x), which helps when you’re trying to match it up with the rest of your gear. Where it stands out is fault handling. It’s rated 100 kA at 480V AC, so it’s built to clear high fault currents without hesitation. That’s the kind of spec you want in places where a bad fault can take out more than just a breaker. It’s also not oversized for what it does. The footprint is reasonable, which matters when you’re working inside a packed panel. Just note that lugs aren’t included, so plan for that.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e350A breaker for higher-load applications\u003c\/li\u003e\n\u003cli\u003e100 kA interrupting rating @ 480V AC for strong fault protection\u003c\/li\u003e\n\u003cli\u003eThermal-magnetic trip (TM230)—simple, proven protection style\u003c\/li\u003e\n\u003cli\u003eFixed overload setting (Ir = 350A)\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip (5–10x In)\u003c\/li\u003e\n\u003cli\u003e3-pole for three-phase systems\u003c\/li\u003e\n\u003cli\u003eCompact enough for tighter panel spaces\u003c\/li\u003e\n\u003cli\u003eBuilt for steady, long-term use\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 3VA5335-7EC31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 350A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\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\u003eTrip Unit:\u003c\/strong\u003e TM230 Thermal Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100 kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e Fixed at 350A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (II):\u003c\/strong\u003e Adjustable, 5–10x In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 9.8\"\u003c\/li\u003e\n\u003cli\u003eWidth: 6.3\"\u003c\/li\u003e\n\u003cli\u003eDepth: 5.9\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\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\u003eMeets standard requirements for molded case circuit breakers\u003c\/li\u003e\n\u003cli\u003eManufactured to Siemens quality standards\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\u003eYou’ll typically see this used in commercial buildings, industrial panels, and equipment feeds where 350A capacity makes sense.
