3VA5270-6EF31-0AA0 - HFAS 70 Amp Circuit Breaker Description
3VA5270-6EF31-0AA0 - HFAS 70 Amp Circuit Breaker
The Siemens 3VA5270-6EF31-0AA0 is a 70 amp, 3-pole breaker from the 3VA5 series. It’s a thermal magnetic unit with fixed settings, so there’s nothing to dial in—it’s ready to go as-is. It handles overloads the way you’d expect, and if there’s a short, it trips fast. With a 35kA rating at 480V, it’s built for systems where fault current isn’t low. It’s also fairly compact for its class, which helps when panel space starts getting tight.
