It’s part of Siemens’ 3VA5 line, built for serious electrical distribution jobs where dependable protection is expected—not optional. This is a 300A, 3-pole thermal-magnetic breaker designed for line protection in commercial and industrial applications. The trip unit is straightforward and reliable: fixed overload protection at 300A, plus an adjustable instantaneous trip (5–10x) to handle short-circuit events—no unnecessary complexity—just solid, predictable performance. With a 65kA interrupting rating at 480V AC, it’s ready for higher fault levels commonly found in larger facilities. It’s also built on a 400A frame, giving you a bit of headroom while keeping the footprint manageable inside your panel. Like most professional-grade breakers, lugs aren’t included, so you can choose the ones that best fit your setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e300 Amp rating for reliable performance in demanding systems\u003c\/li\u003e\n\u003cli\u003e3-pole design for three-phase applications\u003c\/li\u003e\n\u003cli\u003eThe thermal magnetic trip unit (TM230) keeps protection simple and dependable\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip (5–10x) helps match real-world conditions\u003c\/li\u003e\n\u003cli\u003e65kA @ 480V AC interrupting capacity handles high fault currents\u003c\/li\u003e\n\u003cli\u003e400A frame size offers flexibility in system design\u003c\/li\u003e\n\u003cli\u003eH-interrupting class (HJAS) suited for tougher environments\u003c\/li\u003e\n\u003cli\u003eBuilt by Siemens, a name that contractors and engineers trust\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 3VA5330-6EC31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 300A\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\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM230)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 300A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (II):\u003c\/strong\u003e 5–10x adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 65kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 9.8 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\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 the U.S.\u003c\/li\u003e\n\u003cli\u003eDesigned to meet standard North American electrical requirements\u003c\/li\u003e\n\u003cli\u003eManufactured to Siemens’ established quality standards for consistent performance\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\u003eCommercial buildings and tenant build-outs\u003c\/li\u003e\n\u003cli\u003eManufacturing and industrial facilities\u003c\/li\u003e\n\u003cli\u003eMain and sub-distribution panels\u003c\/li\u003e\n\u003cli\u003eEquipment protection where a higher fault current is a concern\u003c\/li\u003e\n\u003cli\u003eUpgrade projects replacing older or undersized breakers\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.
