Product FAQs
5 answersWhat are the trip settings on the Siemens 3VA5225-6EC31-0AA0?
This breaker utilizes a TM230 thermal-magnetic trip unit with Fixed Thermal and Adjustable Magnetic (FTAM) protection. The continuous thermal overload is fixed at 250A. The instantaneous short-circuit pickup is adjustable from 5 to 10 times the rated current, allowing an adjustment range of 1250A to 2500A.
Which legacy Siemens breaker does the 3VA5225-6EC31-0AA0 replace?
It serves as the modern functional equivalent to the legacy HFD63B250, sharing the same 250A rating and 65kAIC at 480VAC interrupting capacity. If upgrading an older panelboard, replacing an FD frame with a 3VA52 frame requires new 3VA-specific mounting hardware.
Does the 3VA5225-6EC31-0AA0 include terminal lugs out of the box?
Siemens catalog numbers ending in -0AA0 ship standard with a nut keeper or punched copper bar connection for busbar mounting. If your installation requires mechanical wire lugs, you must install a compatible lug kit before wiring.
What wire lug kits are compatible with this 250A 3VA52 breaker?
For single-cable applications using 6 AWG to 350 kcmil aluminum or copper wire, use the 3VA9233-0JB12 lug kit. If your installation requires two cables per phase, the 3VA9233-0JJ22 kit accepts two 4 AWG to 300 kcmil conductors.
Can the 3VA5225-6EC31-0AA0 be reverse fed?
Yes. Like most Siemens 3VA5 thermal-magnetic circuit breakers, it features a reverse feed construction. It does not have dedicated line and load restrictions, allowing you to safely supply power from either the top or bottom terminals.
