It’s rated at 35kA at 480V, so it’s built to handle higher fault levels without issues. This unit uses a thermal magnetic trip, which means you’re covered for both overloads and short circuits. The settings are fixed from the factory—overload is set at 125A and instantaneous trip is 10 times that—so there’s nothing to adjust. That’s usually a plus if you just want to install it and know it’s going to behave consistently. It’s part of the Siemens 3VA5 line, so it’s meant for modern distribution systems and standard panel applications. If you’ve worked with Siemens before, this will feel familiar.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e125A rated current\u003c\/li\u003e\n\u003cli\u003e35kA interrupting capacity at 480V\u003c\/li\u003e\n\u003cli\u003e3-pole for three-phase systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip (overload + short circuit protection)\u003c\/li\u003e\n\u003cli\u003eFixed settings (no field adjustment needed)\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x In\u003c\/li\u003e\n\u003cli\u003eBuilt on the 3VA52 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 3VA5212-5ED31-0AA0\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\u003ePoles:\u003c\/strong\u003e 3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 480V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 35kA @ 480V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM210)\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\u003eInstantaneous Trip (Ii):\u003c\/strong\u003e 10x In\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Type:\u003c\/strong\u003e 3VA52 (250 Frame)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 9.65 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\u003eMeets UL requirements for molded case circuit breakers\u003cstrong\u003e.\u003c\/strong\u003e Built for standard compliance in U.S. commercial and industrial electrical systems.\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\u003eGood fit for panelboards, switchboards, and equipment protection in commercial buildings or industrial facilities.
