The Siemens 3VA5330-5EC61-0AA0 circuit breaker is built for that exact situation—steady 300A performance with dependable protection when something goes wrong. This model is part of Siemens’ 3VA5 series, a line widely used in commercial and industrial environments where equipment downtime isn’t an option. It uses a thermal magnetic trip unit, which means it handles both overloads and short circuits without needing a complicated setup. In plain terms: it reacts when it should, and stays out of the way when everything’s running normally. You’re working with a 2-pole breaker in a 3-pole frame, giving you flexibility when fitting it into existing panels. And with a 35 kA interrupting rating at 480V AC, it’s designed to deal with real fault conditions—not just ideal scenarios on paper. It’s the kind of breaker electricians install and don’t have to think about again.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e300 Amp rating for high-demand electrical systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip (TM230) for combined overload and short-circuit protection\u003c\/li\u003e\n\u003cli\u003e35 kA interrupting capacity @ 480V AC for strong fault handling\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip (5–10x In) for better system coordination\u003c\/li\u003e\n\u003cli\u003e2-pole design in a 3-pole frame for flexible installation\u003c\/li\u003e\n\u003cli\u003eFixed overload protection (Ir = 300A) for consistent performance\u003c\/li\u003e\n\u003cli\u003eCompact footprint that fits standard panel setups\u003c\/li\u003e\n\u003cli\u003eBuilt for long-term, dependable operation\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 3VA5330-5EC61-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2 (in 3-pole frame)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e 300A\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 300A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Trip (Ii):\u003c\/strong\u003e 5–10x In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 35 kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.8\" H x 6.3\" W x 5.9\" D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Fixed (FTAM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\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\u003eThe Siemens 3VA5 series is manufactured to meet UL standards for molded case circuit breakers, making it suitable for use in U.S. commercial and industrial electrical systems.
