3VA5220-7EC31-0AA0 - CFAS 200 Amp Circuit Breaker

3VA5220-7EC31-0AA0 - CFAS 200 Amp Circuit Breaker

The Siemens 3VA5220-7EC31-0AA0 is a 200-amp, 3-pole circuit breaker built for straightforward, reliable protection in three-phase systems. It’s part of Siemens’ 3VA5 line, which is commonly used in commercial and industrial setups where you need dependable performance without overcomplicating things. This unit is rated for 100 kA at 480V, making it well-suited for systems where higher fault current is a concern. It uses a thermal magnetic trip unit, meaning overloads are handled with a time delay while short circuits trip instantly. Both protection settings are fixed at the factory—200A for overload and 10x the rated current for instantaneous trips—so there’s nothing to adjust or second-guess in the field. Physically, it’s a compact breaker for its class and fits into standard panel and distribution setups without much hassle. If you’re replacing a similar unit or specifying for a new install, this is the kind of breaker that does its job and stays out of your way.
