3VA5335-6EC61-0AA0 - 350A Class HJAS 2-Pole Circuit Breaker

3VA5335-6EC61-0AA0 - 350A Class HJAS 2-Pole Circuit Breaker

The Siemens 3VA5335-6EC61-0AA0 is a 350-amp breaker built for jobs where you need solid protection without overcomplicating things. It’s part of the 3VA5 line, so you’re getting a unit that’s commonly used in commercial and light industrial setups where reliability is expected—not optional. This is a 2-pole breaker in a 3-pole frame, which comes in handy depending on how your panel is laid out. The overload protection is fixed at 350A, so once it’s in, it just does its job—no adjustments needed. For short circuits, the instantaneous trip can be set between 5 and 10 times the rated current, giving you some control over how it reacts under fault conditions. With a 65kA interrupting rating at 480V, it’s designed to handle high fault currents without becoming the weak point in your system.
