It’s rated at 90 amps with a 3-pole configuration, making it a practical fit for three-phase applications where you just need dependable protection without overcomplicating things. This unit uses a thermal magnetic trip, so it handles overloads and short circuits the way most contractors expect—nothing fancy, just proven protection that works. The overload is fixed at 90 amps, which means there’s no setup to worry about. Install it, wire it, and it’s ready to go. On the short-circuit side, it trips instantly at 10 times the rated current, helping limit damage when something goes wrong. With a 35kA interrupting rating at 480V, it’s capable of handling higher fault conditions found in commercial and light industrial setups. It’s part of Siemens’ 3VA5 line, which has a reputation for being consistent and easy to work with in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e90A rating for typical commercial and industrial loads\u003c\/li\u003e\n\u003cli\u003e3-pole breaker for full three-phase coverage\u003c\/li\u003e\n\u003cli\u003e35kA interrupting capacity at 480V\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip—simple and widely used protection type\u003c\/li\u003e\n\u003cli\u003eFixed overload setting (90A), no adjustments needed\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x current for fast fault response\u003c\/li\u003e\n\u003cli\u003eCompact size that fits well in most panel layouts\u003c\/li\u003e\n\u003cli\u003eBuilt by Siemens, known for consistent electrical components\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 3VA5290-5EF31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 90A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 35kA @ 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Type:\u003c\/strong\u003e Thermal Magnetic (TM240, ATAM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 90A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Protection (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\n\u003cul\u003e\n\u003cli\u003eHeight: 9.65 in\u003c\/li\u003e\n\u003cli\u003eWidth: 6.3 in\u003c\/li\u003e\n\u003cli\u003eDepth: 5.9 in\u003c\/li\u003e\n\u003c\/ul\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 for use in North American electrical systems\u003c\/li\u003e\n\u003cli\u003eMeets standard industry requirements for circuit protection\u003c\/li\u003e\n\u003cli\u003eDesigned for line protection in low-voltage distribution setups\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 and tenant panels\u003c\/li\u003e\n\u003cli\u003eEquipment panels in light industrial settings\u003c\/li\u003e\n\u003cli\u003eManufacturing lines that don’t need adjustable trip units\u003c\/li\u003e\n\u003cli\u003eRetrofit jobs where you want something reliable without extra setup\u003c\/li\u003e\n\u003cli\u003eGeneral three-phase distribution where consistency matters\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.
