3VA4170-6ED34-0AA0 - 70Amp Circuit Breaker

3VA4170-6ED34-0AA0  -  70Amp Circuit Breaker

If you're looking for a circuit breaker that doesn’t flinch under pressure, the Siemens 3VA4170-6ED34-0AA0 delivers exactly that. Built as part of Siemens’ trusted SENTRON 3VA4 series, this 70 amp molded case circuit breaker is designed to protect your electrical systems from overloads and short circuits—without the guesswork or hassle. What makes this breaker stand out is its ability to handle serious fault conditions. With a 65 kA interrupting rating at 480V, it’s built for environments where reliability isn’t optional—it’s critical. The integrated thermal-magnetic trip unit (TM210) keeps things simple and effective. It provides fixed overload protection at 70A and fast-response short-circuit protection at 10 times the rated current. And because space and installation time matter, Siemens keeps it practical. The compact 125A frame size, straightforward terminal connections, and durable build make it easy to install and even easier to trust over the long haul.
