Description
Built for high-capacity power distribution, the 3VA5225-7ED31-0AA0 delivers reliable 3-pole, 250A circuit protection within the SENTRON family. It features a fixed thermal-magnetic trip unit for robust long-time and instantaneous (LI) defense against overloads and short circuits. Designed to mount into Siemens panelboards and switchboards, it requires a strap kit for P-series panels. This current-limiting breaker is HACR rated and replaces the discontinued HHFD63B250 model.Specifications

Product FAQs
7 answersWhat is required to install the 3VA5225-7ED31-0AA0 in a Siemens P2 or P3 panelboard?
You will need a compatible strap kit, such as the BBKVA5262P2S for single horizontal mounting, to properly install this 3VA52 frame breaker into P1, P2, or P3 panelboards.
Can the Siemens 3VA5225-7ED31-0AA0 be reverse fed?
Yes, all Siemens 3VA5 thermal-magnetic molded case circuit breakers are UL listed for reverse feed applications.
Is this 250A circuit breaker 80% or 100% rated?
The 3VA5225-7ED31-0AA0 is a standard 80% rated circuit breaker. It is not marked for continuous operation at 100% of its nominal current.
Which legacy Siemens breaker frames does the 3VA52 series replace?
The 3VA52 frame is the modern replacement for legacy Siemens 250A frames, including the FD6, FXD6, and HFD6 series. Note that mounting hardware and panel strap kits will differ from the older frames.
How is the 3VA5225-7ED31-0AA0 applied in 750VDC systems?
While rated for 100kA at 750VDC, applying a 3-pole thermal-magnetic breaker on high-voltage ungrounded DC systems requires wiring the poles in series to safely interrupt the DC arc. Always follow Siemens DC application guidelines for proper pole wiring.
Are the trip settings adjustable on the 3VA5225-7ED31-0AA0?
No, this breaker features a TM210 thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) settings. It does not offer adjustable trip dials.
What does the '7' in the 3VA5225-7ED31-0AA0 catalog number indicate?
The '7' designates Siemens Class C interrupting capacity, which provides a high interrupting rating of 100kA at 480VAC.
