The Siemens 3VA2325-7HM42-0AA0 is a 4-pole SENTRON molded case circuit breaker rated for 250 A continuous current (Iu) across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The ETU330 electronic trip unit gives you adjustable long-time delay (tr) from 0.5 to 17 s and N-conductor protection that can be set to OFF, 50%, or 100% of the phase current, which matters for 4-wire systems where the neutral must be switched and protected independently. Breaking capacity hits 330 kA at 240 V and 242 kA at 415/440 V, dropping to 187 kA at 500 V and 7.5 kA at 690 V — so on a 480 V distribution panel the SCCR headroom is substantial, but at 690 V the fault-clearing capability narrows to a level that still covers most industrial motor-drive branches.

Frequently asked questions
Where can I buy 3VA2325-7HM42-0AA0 and how do I get a price?
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.
What is the depth of 3VA2325-7HM42-0AA0?
The depth is 110 mm (4.3 in).
What is the width of 3VA2325-7HM42-0AA0?
The width is 184 mm (7.2 in).
Will 3VA2325-7HM42-0AA0 drop into a panel specified around 3VA2110-7HK42-0AA0 without rewiring?
No — the 3VA2325-7HM42-0AA0 is a larger-frame breaker (250 A vs the smaller-frame sibling). The mounting footprint, bus-bar spacing, and lug sizes differ; a panel designed for the 3VA2110 frame would require mechanical and electrical rework to accept this 4-pole 250 A unit.
