It’s an 80-amp, 3-pole unit from the 3VA5 series, built for standard three-phase systems where protection has to be consistent. With a 100kA interrupting rating at 480V, it’s more than capable of handling higher fault levels without hesitation. This model uses a thermal magnetic trip unit, which a lot of contractors still prefer for its simplicity and reliability. The settings are fixed—80A for overload and 10x In for instantaneous trips—so once it’s in place, there’s nothing to tweak or drift out of spec over time. That’s often exactly what you want in a busy panel: install it, trust it, move on. It also fits into a fairly compact footprint for a frame 250 breaker, which helps when space inside the enclosure is tight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRated at 100kA @ 480V for handling higher available fault current\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit—simple, proven, and dependable\u003c\/li\u003e\n\u003cli\u003eFixed 80A overload protection (no field adjustments needed)\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x In for fast short-circuit response.\u003c\/li\u003e\n\u003cli\u003e3-pole configuration for three-phase distribution\u003c\/li\u003e\n\u003cli\u003eCompact size for easier panel integration\u003c\/li\u003e\n\u003cli\u003eBuilt for steady, long-term use in demanding environments\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 3VA5280-7EC31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA52 (3VA5 platform)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 80A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100kA @ 480V\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 (Ir):\u003c\/strong\u003e 80A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous (Ii):\u003c\/strong\u003e 10 × In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.65\" H × 6.3\" W × 5.9\" D\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 molded case circuit breaker.\u003c\/li\u003e\n\u003cli\u003eBuilt to meet standard electrical safety requirements for commercial and industrial use\u003c\/li\u003e\n\u003cli\u003eSuitable where UL-compliant components are required\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 in commercial buildings, light industrial setups, and OEM panels.
