This 70-amp, 3-pole breaker from the 3VA5 line is built for solid, everyday protection in commercial and industrial setups where reliability isn’t optional. What stands out here is the 100kA interrupting rating at 480V—it gives you a comfortable margin in systems where fault current can spike hard. The thermal magnetic trip unit is straightforward and dependable: fixed overload protection at 70A and instantaneous protection set at 10x the rated current—no guesswork, no unnecessary adjustments—just consistent performance. It’s also sized right for practical installs. The 3VA5 frame keeps things compact enough to fit comfortably in most panel configurations without sacrificing capability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100kA @ 480V interrupting capacity handles high fault conditions with confidence\u003c\/li\u003e\n\u003cli\u003e70 amp rating suited for a wide range of commercial and industrial loads\u003c\/li\u003e\n\u003cli\u003e3-pole design for three-phase system protection\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit (TM240) for dependable, no-nonsense operation\u003c\/li\u003e\n\u003cli\u003eFixed overload protection (Ir = 70A)—no drift, no surprises\u003c\/li\u003e\n\u003cli\u003eInstantaneous trip at 10x In for fast fault clearing\u003c\/li\u003e\n\u003cli\u003eCompact 3VA5 frame helps save space inside the panel.\u003c\/li\u003e\n\u003cli\u003eBuilt for long-term use in demanding environments\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\u003eSeries:\u003c\/strong\u003e 3VA52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3VA5270-7EF31-0AA0\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 70A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 100kA @ 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 70A (fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Protection (Ii):\u003c\/strong\u003e 10 × In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.65\" H × 6.3\" W × 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\u003eThis breaker is manufactured to meet UL standards for molded case circuit breakers, making it suitable for use in regulated electrical systems across the U.S. It’s designed with safety and code compliance in mind so that you can install it with confidence in the right application.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYou’ll typically see this breaker used in distribution panels, industrial equipment, and commercial electrical systems where higher interrupting capacity is needed.
