It’s part of the 3VA5 series, so it’s built for consistent performance in everyday power distribution—not overcomplicated, just reliable. You’ve got some flexibility with this one. The overload setting can be adjusted between 240A and 300A, which helps when your load isn’t perfectly fixed. The instantaneous trip range (5x to 10x) also gives you some control over how the breaker reacts to faults, which can help reduce nuisance trips. It uses a 400A frame, so there’s some built-in margin, and the size is typical for this class—nothing unusual to deal with during installation.\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\u003eAdjustable overload range:\u003c\/strong\u003e 240A–300A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal magnetic protection:\u003c\/strong\u003e Thermal magnetic protection (overload + short circuit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous trip setting:\u003c\/strong\u003e 5x–10x\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-pole:\u003c\/strong\u003e 3-pole for three-phase systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame size:\u003c\/strong\u003e 400A frame size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Standard, easy-to-fit design\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 3VA5330-7EF31-0AA0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Siemens 3VA5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmps:\u003c\/strong\u003e 300A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload (Ir):\u003c\/strong\u003e 240A – 300A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstantaneous (Ii):\u003c\/strong\u003e 5x – 10x In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Class:\u003c\/strong\u003e C (CJAS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e Up to 480V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.8\" H x 6.3\" W x 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\u003eUL Listed\u003c\/li\u003e\n\u003cli\u003eMeets standard U.S. safety requirements\u003c\/li\u003e\n\u003cli\u003eSuitable for NEC applications when installed correctly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a straightforward fit for commercial panels, industrial equipment, and general power distribution.
