3VA4170-4ED34-0AA0 - 70Amp Circuit Breaker

3VA4170-4ED34-0AA0  -  70Amp Circuit Breaker

The Siemens 3VA4170-4ED34-0AA0 is a 70 amp, 3-pole molded case circuit breaker built for straightforward, dependable circuit protection in commercial and industrial setups. It’s part of Siemens’ SENTRON 3VA4 line, which is known for doing exactly what it’s supposed to do—protect equipment and keep systems running without unnecessary complexity. This breaker uses a thermal-magnetic trip unit (TM210) with fixed settings. The overload protection is set at 70A, and the instantaneous trip kicks in at 10 times the rated current, helping shut things down quickly during a fault. With a 25 kA interrupting rating at 480V, it’s suitable for a wide range of applications where fault current levels need to be handled safely and predictably. It’s also compact for its class, which makes a difference when panel space is tight. Installation is straightforward, and once it’s in place, it’s designed to stay out of your way. With solid build quality and a long mechanical life, this is the kind of breaker you install and don’t have to keep coming back to.
