Three-pole construction handles three-phase motor circuits, and the built-in phase failure detection provides an additional layer of protection against single-phasing — a common failure mode that cooks motor windings. At 440 kA, it can interrupt a bolted fault on a large transformer secondary without cascading upstream, provided the upstream device is coordinated. Front-face protection class is IP40. If you need shunt trip, UVR, or Modbus, you're looking at a different variant in the 3VA2 family. Maximum power loss is 0.5 W — negligible for panel thermal budgeting. As a Siemens SENTRON product, this MCCB carries the usual compliance documentation (UL, IEC, CSA, CE, RoHS, REACH) — available on request with the RFQ.","metaTitle":"Siemens 3VA2125-0MN32-0AA0 SENTRON MCCB, 25 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2125-0MN32-0AA0 SENTRON molded case circuit breaker, 25 A continuous, 3-pole, ETU350M release, adjustable trip class 10A/10E/20E, 440 kA at 415 V.
