It’s a 300 amp, 3-pole breaker from the 3VA5 series, built for typical commercial and industrial setups where reliability matters more than anything else. Nothing fancy here—and that’s a good thing. It uses a thermal magnetic trip, so it handles overloads steadily and reacts quickly if there’s a short circuit. With a 100 kA rating at 480V AC, it’s more than capable for systems where available fault current is on the higher side. This is the kind of breaker you install and don’t have to think about again.\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 standard commercial and industrial loads\u003c\/li\u003e\n\u003cli\u003e3-pole design for three-phase systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit for simple, dependable protection\u003c\/li\u003e\n\u003cli\u003e100 kA interrupting capacity @ 480V AC for higher fault levels\u003c\/li\u003e\n\u003cli\u003eFixed overload setting (300A)—no guesswork\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip (5–10x) if you need to fine-tune\u003c\/li\u003e\n\u003cli\u003e400A frame keeps it compact for its class\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 3VA5330-7EC31-0AA0\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 300A\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\u003eTrip Type:\u003c\/strong\u003e Thermal Magnetic (TM230)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 100 kA @ 480V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload (Ir):\u003c\/strong\u003e 300A (fixed)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous (Ii):\u003c\/strong\u003e 5–10x adjustable\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 9.8\" H x 6.3\" W x 5.9\" D\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\u003cbr\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\u003eUL Listed\u003c\/li\u003e\n\u003cli\u003eMeets standard U.S. electrical safety requirements\u003c\/li\u003e\n\u003cli\u003eBuilt for consistent performance in commercial 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 used in panelboards, switchgear, and distribution systems in commercial buildings or light industrial facilities.
