3VA5325-5EF31-0AA0 - 250A Class MJAS 3-Pole Circuit Breaker Description
3VA5325-5EF31-0AA0 - 250A Class MJAS 3-Pole Circuit Breaker
If you’re putting together a panel or replacing a breaker in a system that sees real load, you want something that’s going to hold up without a lot of second-guessing. The Siemens 3VA5325-5EF31-0AA0 is a 250-amp, 3-pole breaker that’s commonly used in commercial and light industrial setups where consistency matters more than anything flashy. It uses a thermal magnetic trip, so it handles both overloads and short circuits the way you’d expect—nothing overly sensitive, nothing sluggish—just steady, predictable protection. The adjustable range (200A–250A) is useful too, especially if you’re trying to match it to a specific load or give yourself a little flexibility during install. With a 35 kA rating at 480V, it’s built to deal with higher fault levels without becoming the weak point in the system. It’s part of Siemens’ 3VA5 line, which has been around long enough to be familiar to most electricians and engineers—so there’s no learning curve or surprises when it comes to fit and function.
