Product FAQs
6 answersWhich panelboards are compatible with the 3VA5170-6EC31-0AA0?
This breaker is designed for direct integration into Siemens 3VA panelboards and switchboards. It can also be installed in Siemens P1 panelboards when equipped with the correct mounting adapter kit.
How is the trip unit configured on this breaker?
It utilizes a thermal magnetic trip unit featuring fixed thermal protection for continuous overloads and an adjustable magnetic setting for instantaneous short circuit protection.
Is this 3VA5 breaker suitable for DC voltage systems?
Yes, it is rated for DC applications up to 500VDC, delivering a maximum interrupting capacity of 100kA at that voltage.
What is the mounting method for the 3VA5170-6EC31-0AA0?
This is a feed-thru, panel mount breaker. It bolts directly to the enclosure backpan or mounting plate and connects via lugs, rather than plugging directly onto a panelboard bus.
What protection functions are included in the LI designation?
The LI code specifies that the breaker provides Long-Time (L) protection against sustained overcurrents and Instantaneous (I) protection to clear severe short circuits immediately.
Can the 3VA5 series replace legacy Siemens Sentron breakers?
The 3VA5 line serves as the current generation replacement for older Sentron molded case breakers. Because physical dimensions and mounting hardware differ from legacy ED or FD frames, you must verify panel space and adapter compatibility before upgrading.
