The Siemens 3VA5212-7EC31-0AA0 is exactly that. It’s built for real-world electrical systems where reliability matters more than anything else. This 3-pole Siemens breaker is part of the 3VA5 series, designed to handle everyday commercial and industrial loads without overcomplicating the install. It uses a thermal magnetic trip unit, so it reacts the way you expect—steady protection for overloads and fast action when a short circuit hits. What makes this model stand out is its 100kA interrupting rating at 480V. That’s not just a number—it means this breaker is ready for environments where fault current is higher and mistakes are expensive. It gives you a level of confidence that’s hard to get with lower-rated units. And because the trip settings are fixed, there’s no fine-tuning or second-guessing. You install it, and it does exactly what it’s designed to do—protect your system and stay out of your way.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e125 amp circuit breaker for commercial and industrial applications\u003c\/li\u003e\n\u003cli\u003e3-pole design for three-phase power distribution\u003c\/li\u003e\n\u003cli\u003e100kA @ 480V interrupting rating for high fault current protection\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit (TM230)—simple, proven, and dependable\u003c\/li\u003e\n\u003cli\u003eFixed overload protection (Ir = 125A) for consistent performance\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x In for quick short-circuit response\u003c\/li\u003e\n\u003cli\u003eCompact design that fits well in panels and equipment 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 3VA5212-7EC31-0AA0\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 125A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e Up to 480V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 100kA @ 480V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Type:\u003c\/strong\u003e Thermal Magnetic (TM230)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 125A (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\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\u003eMeets UL standards for molded case circuit breakers\u003c\/li\u003e\n\u003cli\u003eBuilt for compliance with North American electrical codes\u003c\/li\u003e\n\u003cli\u003eManufactured to Siemens quality standards for consistent, long-term use\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\u003eYou’ll typically see this Siemens 125A breaker in commercial buildings, industrial panels, and equipment protection setups.
