The Siemens 3VA5215-5EF31-0AA0 circuit breaker is built for exactly that kind of pressure. Designed for commercial and industrial applications, this 150 amp, 3-pole breaker delivers consistent, no-nonsense protection where it matters most.\u003c\/p\u003e\n\u003cp\u003eWhat sets this model apart is its balance of simplicity and performance. With a thermal magnetic trip unit (TM240), you get dependable overload protection paired with fast short-circuit response—without the need for complicated adjustments. It’s engineered to react when it should, stay stable when it must, and keep your operation moving without interruption.\u003c\/p\u003e\n\u003cp\u003eAnd when fault conditions hit hard, this breaker is ready. With a 35kA interrupting capacity at 480V, it’s built to handle serious electrical events while protecting downstream equipment. That means less risk, less damage, and fewer costly shutdowns.\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\u003e150 Amp Continuous Protection:\u003c\/strong\u003e Ideal for maintaining steady performance in demanding electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35kA @ 480V Interrupting Rating:\u003c\/strong\u003e Handles high fault currents with confidence.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Magnetic Trip (TM240):\u003c\/strong\u003e Combines precision overload protection with rapid short-circuit response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed Protection Settings:\u003c\/strong\u003e Overload (Ir) set at 150A and short-circuit (Ii) at 10x In for consistent, predictable operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Pole Design:\u003c\/strong\u003e Built for three-phase power distribution environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 3VA5 Frame (250 Frame):\u003c\/strong\u003e Saves panel space without sacrificing capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProven Siemens Build Quality:\u003c\/strong\u003e Designed for durability and long-term reliability in real-world conditions.\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 3VA5215-5EF31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 150A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 35kA @ 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e TM240 (Thermal Magnetic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 150A (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\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\u003e\n\u003cstrong\u003eUL Listed:\u003c\/strong\u003e Meets strict U.S. safety and performance standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCode-Ready Design:\u003c\/strong\u003e Suitable for installations requiring NEC compliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial-Grade Components:\u003c\/strong\u003e Built to perform reliably in demanding electrical environments.\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\u003eThis breaker is a strong choice for commercial facilities, industrial plants, and OEM panel builders who need dependable line protection without overcomplication.
