3VA5320-5EC31-0AA0 - 200A Class MJAS 3-Pole Circuit Breaker

3VA5320-5EC31-0AA0 - 200A Class MJAS 3-Pole Circuit Breaker

The Siemens 3VA5320-5EC31-0AA0 is a 200A, 3-pole circuit breaker used in a lot of standard commercial and industrial setups. If you’re dealing with a three-phase panel and need something dependable, this is the kind of breaker people stick with.It’s a thermal magnetic unit, so nothing complicated—overloads are handled the usual way, and the short-circuit trip can be adjusted between 5–10x. That gives you some flexibility depending on how your system is set up. Once it’s in, it just does its job.You’re working with a 400A frame here, along with a 35 kA rating at 480V, so it’s built to handle higher fault levels without issue. Size-wise, it’s not oversized or awkward, which helps when you’re trying to keep a panel clean and organized.

Just keep in mind—lugs aren’t included.
