The Siemens 3VA5340-7EC61-0AA0 is built for exactly that kind of environment—where reliability isn’t a bonus, it’s the baseline. This 400 amp breaker from the 3VA5 family gives you straightforward, dependable protection against overloads and short circuits, without unnecessary complexity. What stands out here is the balance between power and control. You’ve got a 2-pole setup inside a 3-pole frame, which gives you a bit more flexibility when you’re working within existing panel constraints. Add in a 100 kA interrupting rating at 480V, and you’re looking at a breaker that can comfortably handle high fault conditions without hesitation. It’s the kind of component you install and don’t have to think about again—which, frankly, is exactly what you want.\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\u003e400 Amp Capacity –\u003c\/strong\u003e Built for high-demand systems that can’t afford interruptions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100 kA @ 480V AC –\u003c\/strong\u003e Strong fault-clearing capability for tougher applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Magnetic Trip Unit (TM230) –\u003c\/strong\u003e Simple, proven protection against overloads and short circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed Overload Protection –\u003c\/strong\u003e Set at 400A for consistent, predictable performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Instantaneous Trip (5–10x) –\u003c\/strong\u003e Gives you some control over short-circuit response\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Pole in 3-Pole Frame –\u003c\/strong\u003e Easier integration into a wider range of panel setups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Footprint –\u003c\/strong\u003e Doesn’t take up more space than it needs to\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\u003eManufacturer:\u003c\/strong\u003e Siemens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3VA5340-7EC61-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries \/ Type:\u003c\/strong\u003e 3VA53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2 (mounted in a 3-pole frame)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100 kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic (TM230)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 400A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (II):\u003c\/strong\u003e 5–10x range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 9.8 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\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Class:\u003c\/strong\u003e Class C (CJAS)\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\u003e\n\u003cstrong\u003eUL Listed:\u003c\/strong\u003e This breaker is UL listed, which means it meets established safety and performance standards for use in commercial and industrial electrical systems.
