That’s exactly what you get with the Siemens 3VA5245-5ED31-0AA0. This is a 45 amp, 3-pole circuit breaker built for solid, everyday performance in commercial and industrial setups. It uses a thermal magnetic trip unit, which means it handles both overloads and short circuits the way you’d expect—no surprises. One thing people like about this model is that it’s factory set. The overload protection is fixed at 45 amps, and the instantaneous trip is set at 10 times that. So there’s no adjusting, no dialing things in—install it, and you’re good to go. It also brings a 35kA interrupting rating at 480V, which gives you the confidence to use it in higher fault environments without worrying about whether it can handle the 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\u003eStraightforward protection –\u003c\/strong\u003e Thermal magnetic operation covers overloads and short circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo setup needed –\u003c\/strong\u003e Fixed trip settings save time during installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35kA interrupting rating @ 480V –\u003c\/strong\u003e Handles demanding electrical conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-pole configuration –\u003c\/strong\u003e Designed for three-phase systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsistent performance –\u003c\/strong\u003e Trips when it should, every time\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact footprint –\u003c\/strong\u003e Fits neatly into standard panel 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 3VA5245-5ED31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Type:\u003c\/strong\u003e 3VA52 (250 Frame)\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 45A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e Up to 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 35kA @ 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 45A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (Ii):\u003c\/strong\u003e 10 × In\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 U.S.\u003c\/li\u003e\n\u003cli\u003eBuilt to meet industry safety and performance standards\u003c\/li\u003e\n\u003cli\u003eManufactured with compliance to applicable environmental guidelines\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\u003eThis breaker fits right into places where reliability matters and downtime costs money: Commercial buildings Industrial equipment and machinery Manufacturing facilities Distribution panels Any three-phase system that needs dependable protection\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.
