The Siemens 3VA5330-7EC61-0AA0 is the kind of unit you install and move on from, because it handles what it’s supposed to without drama. It’s rated at 300 amps and uses a thermal magnetic trip unit, so it reacts to both sustained overloads and sudden faults without delay. There’s no fine-tuning needed on the overload side—it’s fixed at 300A. That’s usually a plus in real-world use since it removes the chance of someone setting it wrong. For short-circuit conditions, you still get an adjustable instantaneous trip range (5 to 10 times the rated current), which gives you some room to match the system you’re working with. It also carries a 100kA interrupting rating at 480V AC, so it’s built for environments where available fault current is on the higher side. The 2-pole setup sits in a 3-pole frame, which can make retrofits or panel standardization a little easier depending on your layout. Not flashy, but that’s the point—it just works.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRated at 300A for higher load applications\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit (TM230) handles overloads and short circuits\u003c\/li\u003e\n\u003cli\u003e100kA interrupting capacity at 480V AC\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip adjustable from 5–10x\u003c\/li\u003e\n\u003cli\u003eFixed overload setting (300A) keeps things simple\u003c\/li\u003e\n\u003cli\u003e2-pole breaker in a 3-pole frame\u003c\/li\u003e\n\u003cli\u003eSized to fit typical commercial and industrial panels\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 3VA5330-7EC61-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 400A\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 2 (in 3-pole frame)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e TM230 (Thermal Magnetic)\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 100kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.8 in (H) × 6.3 in (W) × 5.9 in (D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Class:\u003c\/strong\u003e C (CJAS)\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\u003eBuilt to meet UL standards for molded case circuit breakers, so it aligns with common U.S. electrical requirements for safety and 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 with larger electrical loads\u003c\/li\u003e\n\u003cli\u003eIndustrial equipment and machinery\u003c\/li\u003e\n\u003cli\u003eDistribution panels and switchboards\u003c\/li\u003e\n\u003cli\u003eFacilities where higher fault current is a factor\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.
