3VA5270-7ED31-0AA0 - CFAS 70 Amp Circuit Breaker Description
3VA5270-7ED31-0AA0 - CFAS 70 Amp Circuit Breaker
The Siemens 3VA5270-7ED31-0AA0 is a 70-amp, 3-pole breaker built for jobs where fault current is a real concern. With a 100kA rating at 480V, it’s meant to handle serious interruptions without hesitation. This is part of Siemens’ 3VA5 line, so you’re getting a design that’s widely used in commercial and industrial setups. It uses a thermal magnetic trip unit with fixed settings. Overload protection is locked at 70 amps, and the instantaneous trip is set at 10 times that. No adjustments, no extra setup—install it and move on. The frame is compact for its class, which helps when panel space is tight.
