No extra complexity—just solid performance where it counts. This model uses a thermal magnetic trip unit (TM230), so you’re covered on both overloads and short circuits. The overload setting is fixed at 400A, which takes adjustment errors off the table. For short-circuit protection, the instantaneous trip can be set between 5 to 10 times the rated current, giving you some flexibility depending on your setup. It’s a 2-pole breaker in a 3-pole frame, which makes it easier to work into existing panels when space or configuration is tight. With a 35 kA rating at 480V AC, it’s designed to handle higher fault levels without hesitation. If you need something dependable that doesn’t require constant attention, 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\u003eRated for 400 amps in high-load applications\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit for combined protection\u003c\/li\u003e\n\u003cli\u003e35 kA interrupting capacity at 480V AC\u003c\/li\u003e\n\u003cli\u003e2-pole design housed in a 3-pole frame\u003c\/li\u003e\n\u003cli\u003eFixed overload setting helps avoid setup mistakes\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip (5–10x) for short-circuit response\u003c\/li\u003e\n\u003cli\u003eCompact size for easier panel integration\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 3VA5340-5EC61-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\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\u003eTrip Unit:\u003c\/strong\u003e TM230 Thermal Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 35 kA @ 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Protection:\u003c\/strong\u003e Fixed at 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous Trip:\u003c\/strong\u003e 5–10x rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.8\" H × 6.3\" W × 5.9\" D\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\u003e\n\u003cstrong\u003eIndustry Standards:\u003c\/strong\u003e This breaker is UL listed, which means it meets standard safety requirements for use in the U.S. It’s designed for consistent performance in environments where reliability matters.\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\u003eCommercial distribution panels\u003c\/li\u003e\n\u003cli\u003eIndustrial equipment and machinery\u003c\/li\u003e\n\u003cli\u003eFacilities with higher amperage demands\u003c\/li\u003e\n\u003cli\u003eUpgrade or replacement projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
