It’s a 40-amp, 3-pole unit built on the 3VA5 platform, designed for solid, everyday protection in commercial and industrial systems. What stands out here is the 100kA interrupting rating at 480V. That gives you a comfortable margin in higher fault environments, which is exactly where cheaper breakers tend to fall short. This one doesn’t. It handles overloads with a fixed 40A setting and trips instantly at 10 times the current when a short circuit hits. Simple, predictable, and effective. It’s not trying to be overly complicated—and that’s a good thing. You install it, wire it up, and it does its job in the background.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40 Amp rating with fixed overload protection—no adjustments needed\u003c\/li\u003e\n\u003cli\u003e100kA interrupting capacity at 480V for higher fault applications\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip for straightforward, reliable protection\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x In to quickly clear short circuits\u003c\/li\u003e\n\u003cli\u003e3-pole configuration for standard three-phase systems\u003c\/li\u003e\n\u003cli\u003eBuilt on the 3VA52 frame (250A frame size)\u003c\/li\u003e\n\u003cli\u003eC-Interrupting Class (CFAS) for demanding electrical setups\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 3VA5240-7ED31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siemens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100kA @ 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e TM210 (Thermal Magnetic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 40A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (Ii):\u003c\/strong\u003e 10 × In (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Type:\u003c\/strong\u003e 3VA52 (250A frame)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\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\u003eSuitable for use in compliant commercial and industrial installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCommercial buildings and distribution panels\u003c\/li\u003e\n\u003cli\u003eIndustrial equipment and machinery circuits\u003c\/li\u003e\n\u003cli\u003eOEM panel builds\u003c\/li\u003e\n\u003cli\u003eRetrofit jobs where a higher interrupting capacity is needed\u003c\/li\u003e\n\u003cli\u003e480V three-phase systems\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.
