3VA5290-5ED31-0AA0 - MFAS 90 Amp Circuit Breaker Description
3VA5290-5ED31-0AA0 - MFAS 90 Amp Circuit Breaker
When you're working with electrical systems that can't afford downtime, you want a breaker that just does its job—no surprises. The Siemens 3VA5290-5ED31-0AA0 is built for that kind of reliability.
This is a 90-amp, 3-pole circuit breaker from the Siemens 3VA5 series, designed for commercial and industrial use where consistent protection matters. With a 35kA interrupting rating at 480V, it's capable of handling serious fault conditions without putting your equipment at risk.
One thing that stands out here is the thermal magnetic trip unit (TM210). It's factory set, so there's nothing to adjust in the field. Overload protection is fixed at 90 amps, and short-circuit protection trips at 10 times the rated current. That kind of setup is ideal if you want something straightforward and dependable without extra configuration.
It's a practical choice for electricians and maintenance teams who prefer equipment that's easy to install and performs the same way every time.
