3VA5335-7EC61-0AA0 - 350A Class CJAS 2-Pole Circuit Breaker

3VA5335-7EC61-0AA0 - 350A Class CJAS 2-Pole Circuit Breaker

The Siemens 3VA5335-7EC61-0AA0 is a 350-amp, 2-pole breaker meant for straightforward line protection. It’s part of the 3VA5 series, so you’re getting a newer design that’s built for modern panels and higher fault levels. This one uses a thermal magnetic trip, so nothing complicated. The overload is fixed at 350A, and the short-circuit trip can be adjusted between 5 and 10 times the rated current. That gives you some flexibility without turning it into a programming exercise. It’s built on a 400A frame, even though it’s only 2 poles. That’s normal for this style and usually makes it easier to fit into existing gear. It’s also rated 100 kA at 480V, so it’s not going to struggle in systems with higher available fault current. Just be aware—no lugs included.
