The Siemens 3VA5212-7EF31-0AA0 is the kind you install when you want it done right the first time. This is a 125-amp, 3-pole breaker built on Siemens’ 3VA5 platform, and it’s designed for real-world conditions—not just specs on paper. With a 100kA interrupting rating at 480V, it’s ready for high fault current situations where fewer breakers aren’t enough. It uses a thermal magnetic trip unit, which most pros prefer for its reliability and straightforward operation. Overload protection is set to 125 amps, and the instantaneous trip is set to 10 times the rated current. In other words, it reacts fast when there’s a problem, without needing constant adjustments or fine-tuning. It’s also compact for its class, which makes a difference when panel space is tight. Whether you’re replacing an existing unit or building out a new system, this breaker fits in without creating headaches.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e100kA interrupting rating @ 480V:\u003c\/strong\u003e handles high fault current with confidence\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e125 amp rating:\u003c\/strong\u003e a go-to size for many commercial and industrial setups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal magnetic trip:\u003c\/strong\u003e simple, proven protection that works\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed overload setting:\u003c\/strong\u003e no adjustments, no surprises\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous trip at 10x In:\u003c\/strong\u003e quick response to short circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-pole configuration:\u003c\/strong\u003e designed for three-phase systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 250 frame design:\u003c\/strong\u003e easier installs in tighter panels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-class (CFAS):\u003c\/strong\u003e built for more demanding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siemens\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3VA5212-7EF31-0AA0\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA52 \/ 3VA5 Frame 250\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\u003eAmperage:\u003c\/strong\u003e 125A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100kA @ 480V\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 Protection (Ir):\u003c\/strong\u003e 125A (fixed)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (Ii):\u003c\/strong\u003e 10 × In\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e9.65\" H × 6.3\" W × 5.9\" D\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\u003e\n\u003cstrong\u003eUL Listed:\u003c\/strong\u003e for use in U.S. electrical systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIEC Alignment:\u003c\/strong\u003e Designed to align with IEC standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoHS compliant:\u003c\/strong\u003e for reduced hazardous materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Suitability:\u003c\/strong\u003e Suitable for applications where safety and code compliance are critical\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYou’ll typically see this breaker used in: Commercial buildings and office spaces Industrial panels and equipment protection Manufacturing facilities Data centers and critical power systems Retrofit or replacement projects using Siemens gear\u003cbr\u003e\n\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.
