It’s built for dependable protection in real-world conditions—whether that’s a busy commercial panel or a demanding industrial setup. This is a 90-amp, 3-pole breaker from Siemens’ 3VA5 series, designed to handle serious fault conditions with a 100kA interrupting rating at 480V. In practical terms, that means it’s ready to step in fast when something goes wrong, helping prevent damage to your equipment and keeping downtime to a minimum. It uses a thermal magnetic trip unit (TM240) with fixed settings. The overload protection is set at 90 amps, and the instantaneous trip kicks in at 10 times that. No adjustments, no fine-tuning—just consistent protection that works the way it should right out of the box. If you prefer equipment that’s straightforward, reliable, and backed by a well-known name, this breaker fits the bill.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100kA interrupting capacity at 480V for high fault protection\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit for reliable, proven performance\u003c\/li\u003e\n\u003cli\u003eFixed settings mean no setup or calibration required.\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x rated current for fast response\u003c\/li\u003e\n\u003cli\u003eCompact size makes it easier to work in tight panels.\u003c\/li\u003e\n\u003cli\u003eBuilt for long-term use in commercial and industrial systems\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\u003ePart Number:\u003c\/strong\u003e 3VA5290-7EF31-0AA0\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA52\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 100kA @ 480V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM240, ATAM)\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\u003eShort-Circuit Protection (Ii):\u003c\/strong\u003e 10 × In\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\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 the United States\u003c\/li\u003e\n\u003cli\u003eMeets standard industry safety and performance requirements\u003c\/li\u003e\n\u003cli\u003eManufactured to Siemens quality standards\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 is a solid choice for panelboards, switchgear, and distribution systems in commercial buildings or industrial environments.
