It’s a 90-amp, 3-pole unit built on Siemens’ 3VA5 platform, designed for everyday use in commercial and industrial systems where failure isn’t an option. With a 35kA interrupting rating at 480V, it’s ready for higher fault conditions without hesitation. Inside, you’ve got a thermal-magnetic trip unit, so it handles overloads and short circuits the way it should—nothing fancy, just dependable protection that reacts when it needs to. The settings are fixed, which most guys actually prefer. No adjustments, no second-guessing—install it, wire it, move on. Physically, it’s compact enough to fit comfortably in most panel setups, but still built with the kind of weight and feel you expect from Siemens. This is the kind of breaker contractors, maintenance teams, and panel builders keep coming back to because it just does its job.\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\u003e90 amp rating:\u003c\/strong\u003e for standard commercial and industrial loads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-pole configuration:\u003c\/strong\u003e for three-phase systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35kA interrupting capacity at 480V:\u003c\/strong\u003e handles higher fault levels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal-magnetic trip unit:\u003c\/strong\u003e for straightforward, reliable protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed trip settings:\u003c\/strong\u003e no setup or calibration needed\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePart of the Siemens 3VA5 series (250 frame):\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBuilt for consistent performance over time\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siemens\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3VA5290-5EC31-0AA0\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\u003eFrame Size:\u003c\/strong\u003e 250\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\u003eAmperage:\u003c\/strong\u003e 90A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 35kA @ 480V\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\u003eOverload Protection (Ir):\u003c\/strong\u003e 90A (fixed)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Trip (Ii):\u003c\/strong\u003e 10x rated current\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.65\" H × 6.3\" W × 5.9\" D\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Class:\u003c\/strong\u003e M (MFAS)\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\u003eMeets UL standards for molded case circuit breakers\u003c\/li\u003e\n\u003cli\u003eDesigned for use in North American electrical systems\u003c\/li\u003e\n\u003cli\u003eManufactured with durable internal components for long service life\u003c\/li\u003e\n\u003cli\u003eSuitable for installations requiring UL-listed protection equipment\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\u003eThis breaker makes sense anywhere you need dependable, no-nonsense protection:\u003c\/li\u003e\n\u003cli\u003eCommercial buildings and facility panels\u003c\/li\u003e\n\u003cli\u003eIndustrial equipment and machinery circuits\u003c\/li\u003e\n\u003cli\u003eOEM panel builds\u003c\/li\u003e\n\u003cli\u003eReplacement or upgrade jobs\u003c\/li\u003e\n\u003cli\u003eGeneral three-phase power distribution\u003cbr\u003e\n\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.
