This one does. The Siemens 3VA5240-5ED31-0AA0 is a straightforward, no-drama 40 amp, 3-pole circuit breaker built for real electrical systems—not lab conditions. You install it, it protects, and you move on. That’s the whole point. With a 35kA interrupting rating at 480V, it’s ready for serious fault conditions. The thermal magnetic trip handles both overloads and sudden shorts without needing constant tweaking. Everything is factory set, so there’s nothing to dial in or second-guess later. It’s part of the 3VA5 line, which a lot of contractors stick with for a reason—it’s consistent. No surprises, no weird behavior, just solid protection where you need it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40A rating for dependable circuit protection\u003c\/li\u003e\n\u003cli\u003e35kA @ 480V interrupting capacity for higher fault levels\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip reacts to both overloads and short circuits\u003c\/li\u003e\n\u003cli\u003eFixed settings—install it and you’re done\u003c\/li\u003e\n\u003cli\u003e3-pole design for three-phase applications\u003c\/li\u003e\n\u003cli\u003eCompact frame that doesn’t eat up panel space\u003c\/li\u003e\n\u003cli\u003eBuilt to handle everyday commercial and industrial use\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 3VA5240-5ED31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame:\u003c\/strong\u003e 3VA52 (250A frame)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmps:\u003c\/strong\u003e 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA.I.C.:\u003c\/strong\u003e 35kA @ 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM210)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload (Ir):\u003c\/strong\u003e 40A fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous (Ii):\u003c\/strong\u003e 10x In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\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\u003c\/li\u003e\n\u003cli\u003eMeets standard U.S. electrical safety requirements\u003c\/li\u003e\n\u003cli\u003eBuilt with durable, field-proven components\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 panels\u003c\/li\u003e\n\u003cli\u003eIndustrial equipment\u003c\/li\u003e\n\u003cli\u003eThree-phase distribution systems\u003c\/li\u003e\n\u003cli\u003eManufacturing environments\u003c\/li\u003e\n\u003cli\u003eReplacement for existing Siemens setups\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.
