The Siemens 3VA5335-5EC31-0AA0 is built for those kinds of systems—where you need protection you don’t have to think about twice. This is a 3-pole breaker from the 3VA5 line, commonly used in commercial and industrial panels. It uses a thermal magnetic trip unit, so it handles both overloads and short circuits in a straightforward, proven way. The overload setting is fixed at 350 amps, and the instantaneous trip can be adjusted between 5 and 10 times that, depending on what your system calls for. It’s rated at 35 kA at 480V AC, which puts it in the range for handling real fault conditions—not just minor issues. In other words, when something goes wrong, this breaker is designed to react quickly and help limit the damage. Physically, it’s compact for a 400A frame, so it won’t eat up more panel space than it needs to. One thing to note—lugs aren’t included, so you’ll want to 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\u003e350 amp capacity for higher-load applications\u003c\/li\u003e\n\u003cli\u003e3-pole configuration for three-phase systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic protection (overload + short circuit)\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip (5–10x range)\u003c\/li\u003e\n\u003cli\u003e35 kA interrupting rating at 480V AC\u003c\/li\u003e\n\u003cli\u003eFixed 350A overload setting\u003c\/li\u003e\n\u003cli\u003ePart of the Siemens 3VA5 \/ 3VA53 family\u003c\/li\u003e\n\u003cli\u003eDesigned for consistent, day-to-day reliability\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 3VA5335-5EC31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5 (3VA53)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 350A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 35 kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM230)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 350A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Trip (Ii):\u003c\/strong\u003e 5–10x adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e9.8\" H\u003c\/li\u003e\n\u003cli\u003e6.3\" W\u003c\/li\u003e\n\u003cli\u003e5.9\" D\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 standard U.S. applications\u003c\/li\u003e\n\u003cli\u003eSuitable for installations following NEC requirements\u003c\/li\u003e\n\u003cli\u003eManufactured to meet typical commercial and industrial standards\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\u003eThis is the kind of breaker you’ll usually find in commercial buildings, industrial facilities, and larger distribution panels.
