Product FAQs
7 answersWhich legacy Siemens breakers can the 3VA5217-6EC31-0AA0 replace?
This 3VA5 series breaker is the direct modern replacement for legacy Siemens HFD63B175 and HFXD63B175 molded case circuit breakers.
What panelboards are compatible with the 3VA5217-6EC31-0AA0?
This breaker is designed for seamless integration into Siemens 3VA panelboards and switchboards. It can also be installed in legacy Siemens P2 panelboards when using the required mounting kit.
What does the FTAM designation mean for the 3VA5217-6EC31-0AA0 trip unit?
FTAM stands for Fixed Thermal, Adjustable Magnetic. The TM230 trip unit provides a fixed 175A threshold for long-time overload protection, while allowing you to adjust the instantaneous short-circuit magnetic trip setting to suit your specific application.
What frame size is the 3VA5217-6EC31-0AA0?
While configured for a 175A continuous current, this unit is built on the Siemens 3VA52 frame, which has a maximum capacity of 250A.
How is the 3VA5217-6EC31-0AA0 mounted in an enclosure?
It is primarily designed as a feed-thru, panel-mount breaker for switchboards and panelboards. However, it can also be adapted for DIN-rail mounting using the correct Siemens accessory bracket.
Can the 3VA5217-6EC31-0AA0 be used in 100 percent rated applications?
No, this specific catalog number is standard rated, meaning continuous loads should not exceed 80 percent of its 175A capacity. Applications requiring a 100 percent continuous rating will need a different variant.
Does the 3VA5217-6EC31-0AA0 include ground fault protection?
No, this breaker is equipped with a TM230 thermal-magnetic trip unit that provides long-time (L) and instantaneous (I) protection only. It does not include ground fault (G) or short-time (S) protection functions.
