It’s a 225A, 3-pole unit from the 3VA5 series, built for everyday commercial and industrial distribution—no extra bells—just dependable protection where it counts. It uses a thermal magnetic trip unit, so it reacts to both overloads and short circuits without any complicated add-ons. The interrupting rating is 35 kA at 480V, which gives you a comfortable margin in systems where the available fault current isn’t low. That matters more in the real world than most spec sheets let on. What I like here is the balance. The overload protection is fixed at 225A, so there’s nothing to dial in or second-guess during install. At the same time, you still get an adjustable instantaneous trip (5–10x), which helps when dealing with motors or equipment that pull hard on startup. It’s simple, but not limiting.\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\u003eHandles both overloads and short circuits:\u003c\/strong\u003e with a thermal magnetic trip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35 kA interrupting rating at 480V AC:\u003c\/strong\u003e for solid fault protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e225A rating:\u003c\/strong\u003e covers a wide range of typical applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-pole setup:\u003c\/strong\u003e for standard three-phase systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed overload setting:\u003c\/strong\u003e install it and move on\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable instantaneous trip:\u003c\/strong\u003e helps reduce nuisance trips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt on a 400A frame:\u003c\/strong\u003e for consistent performance over time\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraightforward design:\u003c\/strong\u003e that’s easy to work with\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 3VA5322-5EC31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 225 Amps\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 TM230 (thermal magnetic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 225A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Trip (Ii):\u003c\/strong\u003e Adjustable, 5–10x\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\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e M (MJAS)\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 Requirements:\u003c\/strong\u003e This breaker meets UL requirements for low-voltage circuit protection, making it suitable for code-compliant installations in commercial and industrial environments.\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 in panelboards, switchgear, and distribution setups where loads are steady, and reliability matters more than constant adjustability.
