Front protection is IP40 — fine for a dry indoor panel, but not for washdown zones. ## Current derating and thermal limits That's a shallow slope — the breaker doesn't shed much capacity until you're well above typical panel ambient. Maximum power loss is 9 W, which is modest for a 3-pole 25 A frame. The storage limits govern handling and warehousing, not running conditions. The 3VM1125-5EE32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. No trip indicator on the front, so you'll need to read the handle position or wire an auxiliary contact separately if remote status is required.","metaTitle":"Siemens 3VM1125-5EE32-0AA0 SENTRON MCCB, 25 A, 3-Pole, 187 k","metaDescription":"Siemens 3VM1125-5EE32-0AA0 SENTRON molded case circuit breaker, 25 A, 3-pole, TM220 trip unit.

The 3VM series is the economy line; the 3VA series adds modular accessories and higher SCCR options. Panel cutouts are similar, but verify the depth before swapping — the 3VA frame is slightly deeper."},{"question":"Where can I buy 3VM1125-5EE32-0AA0 and get current pricing?","answer":"This part is sourced to order against an RFQ through independent distribution.
