It’s part of the 3VA5 series, built for consistent protection without unnecessary complexity. This unit uses a thermal magnetic trip system. That means it handles overloads over time and reacts quickly to short circuits. You also get some flexibility—overload protection can be adjusted from 240A up to 300A, and the instantaneous trip can be set between 5 and 10 times the rated current. That helps when you’re trying to match the breaker to your actual load conditions instead of forcing a fixed setup. With a 65 kA interrupting rating at 480V AC, it’s suitable for systems where higher fault current is a concern. It’s a 400A frame, so you’ve got some headroom in the design as well. Physically, it’s compact enough to fit into most standard panel configurations, but still solidly built the way you’d expect from Siemens.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e300 amp rating for three-phase systems\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip (overload + short circuit protection)\u003c\/li\u003e\n\u003cli\u003eAdjustable overload range: 240A–300A\u003c\/li\u003e\n\u003cli\u003eAdjustable instantaneous trip: 5x–10x In\u003c\/li\u003e\n\u003cli\u003e65 kA interrupting capacity at 480V AC\u003c\/li\u003e\n\u003cli\u003e3-pole configuration\u003c\/li\u003e\n\u003cli\u003e400A frame size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3VA5330-6EF31-0AA0\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 3VA53 \/ 3VA5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmps:\u003c\/strong\u003e 300A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e 400A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e TM240 (thermal magnetic)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverload Setting (Ir):\u003c\/strong\u003e 240–300A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-Circuit Setting (Ii):\u003c\/strong\u003e 5–10x In\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 65 kA @ 480V AC (Class H)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.8\" H × 6.3\" W × 5.9\" D\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLugs:\u003c\/strong\u003e Not included\u003cbr\u003e\n\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\u003eBuilt to meet UL standards for low-voltage circuit protection.
