That SCCR curve tells you this breaker handles high-fault scenarios at lower voltages but derates significantly above 440 V — plan the upstream coordination accordingly. ## Ratings that drive the fit Continuous current rating holds flat at 250 A from 40 °C through 50 °C ambient, then steps down: 243.3 A at 55 °C, 236.5 A at 60 °C, 229.8 A at 65 °C, and 223 A at 70 °C. Three-pole format, 105 mm wide by 158 mm tall by 70 mm deep — the 70 mm depth is shallower than many MCCBs in this class, so it tucks into a standard 200 mm deep enclosure with room for wiring gutters. No official successor exists because none is needed.","metaTitle":"Siemens 3VM1225-5ED32-0AA0 SENTRON MCCB, 250 A, 3-Pole, 70 m","metaDescription":"Siemens SENTRON 3VM1225-5ED32-0AA0 molded case circuit breaker, 250 A rated at 40-50 °C, 3-pole, 70 mm depth.

The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time."},{"question":"What is the closest functional alternative to 3VM1225-5ED32-0AA0?","answer":"The 3VA1112-5EE32-0AA0 is a close sibling in the same SENTRON family, but it uses a different release and frame size. The 3VM1225-5ED32-0AA0 has a TM210 release rated 250 A; the 3VA1112-5EE32-0AA0 carries a different release and amp rating. Verify the release type and continuous current before substituting — they are not drop-in interchangeable without rewiring the protection settings."},{"question":"Will 3VM1225-5ED32-0AA0 drop into a panel specified around 3VA1112-5EE32-0AA0 without rewiring?","answer":"Not without checking the mounting footprint and connection terminals. The 3VM1225-5ED32-0AA0 is 105 mm wide by 158 mm tall by 70 mm deep; the 3VA1112-5EE32-0AA0 may have different dimensions and terminal spacing. Compare the physical outline and lug positions before assuming a direct swap."},{"question":"What compliance documentation does Siemens provide for 3VM1225-5ED32-0AA0?","answer":"As a SENTRON MCCB, this breaker carries IEC 60947-2 certification for low-voltage switchgear.
