3VA4170-5ED34-0AA0 - 70Amp Circuit Breaker Description
3VA4170-5ED34-0AA0 - 70Amp Circuit Breaker
The Siemens 3VA4170-5ED34-0AA0 is the kind of circuit breaker you install and don’t have to think about again. It’s built for consistent protection in everyday commercial and industrial applications—nothing flashy, just solid performance where it counts. Rated at 70 amps with a 3-pole configuration, this molded case circuit breaker is designed for three-phase systems that need reliable, predictable protection. It uses a thermal-magnetic trip unit (TM210) with fixed settings, so there’s no adjusting or fine-tuning required. What you get is straightforward overload protection at 70A and fast response to short circuits at 10 times the rated current. With an interrupting capacity of 35 kA at 480V, it’s more than capable of handling high fault conditions. That makes it a practical choice for panelboards, switchboards, and equipment where protection isn’t optional. Another thing worth noting—this breaker keeps a relatively compact footprint for its class. If you’re working in a tight panel or upgrading existing gear, that can make installation a lot easier.
