The Siemens 3VA5210-5EF31-0AA0 is exactly that. It’s a 100-amp, 3-pole breaker built for dependable protection in three-phase systems, whether you’re working in a commercial panel or an industrial setup. This model uses a thermal magnetic trip unit, which means it reacts automatically to overloads and short circuits without any extra setup. No adjustments, no guesswork. Once installed, it quietly runs in the background—protecting your equipment and helping prevent costly downtime. With a 35 kA interrupting rating at 480V, it’s ready to handle higher fault currents with confidence. If you need a breaker that’s straightforward, reliable, and built by a name that’s been trusted in electrical systems for decades, this one fits the bill.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100 amp, 3-pole breaker for three-phase applications\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip for fast, automatic protection\u003c\/li\u003e\n\u003cli\u003e35kA interrupting rating at 480V\u003c\/li\u003e\n\u003cli\u003eFixed trip settings—simple and predictable\u003c\/li\u003e\n\u003cli\u003eCompact design for easy panel or switchgear installation\u003c\/li\u003e\n\u003cli\u003eDesigned for long-term, dependable use\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 3VA5210-5EF31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 250\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 100A\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 Type:\u003c\/strong\u003e Thermal Magnetic (TM240)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection (Ir):\u003c\/strong\u003e 100A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (Ii):\u003c\/strong\u003e 10x In (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.65\" H x 6.3\" W x 5.9\" D\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 North American applications\u003c\/li\u003e\n\u003cli\u003eMeets standard electrical safety and performance requirements\u003c\/li\u003e\n\u003cli\u003eManufactured under strict quality control standards\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 great fit for commercial buildings, industrial equipment, and power distribution panels where you need reliable, no-fuss protection.
