The Siemens 3VA5270-5EF31-0AA0 is built for exactly that—steady, predictable protection without the need to constantly tweak or second-guess your setup. This is a 70 amp, 3-pole breaker from the 3VA5 series, designed for line protection in commercial and industrial environments. It uses a thermal magnetic trip unit, which means it handles both overloads and short circuits in a straightforward, time-tested way. The overload protection is fixed at 70 amps, and the instantaneous trip is set at 10 times that—so when a fault hits, it reacts fast and gets things under control. With a 35kA interrupting rating at 480V, it’s more than capable of handling higher fault levels found in many modern systems. And because it’s part of the 3VA52 frame family, you’re getting a compact design that doesn’t eat up unnecessary space inside your panel. Bottom line—this is the kind of breaker you install and don’t have to think about again. It just does its job.\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\u003e70 amp rating:\u003c\/strong\u003e for dependable circuit protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-pole design:\u003c\/strong\u003e for three-phase systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35kA interrupting capacity:\u003c\/strong\u003e at 480V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal magnetic trip unit (TM240):\u003c\/strong\u003e for combined protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed trip settings:\u003c\/strong\u003e no adjustments needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous trip:\u003c\/strong\u003e at 10× rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 3VA52 frame:\u003c\/strong\u003e helps save panel space\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 3VA5270-5EF31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 3VA52\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\u003eInterrupting Rating:\u003c\/strong\u003e 35kA @ 480V\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 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\u003e\n\u003cstrong\u003eUL Listed:\u003c\/strong\u003e for use in North American electrical systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufactured:\u003c\/strong\u003e to Siemens quality standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable:\u003c\/strong\u003e for installations requiring NEC compliance\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 commercial buildings, industrial panels, and equipment setups where reliability matters more than adjustability.
