Three poles, 800 V rated insulation voltage, and a front-side IP40 protection class that keeps dust and tools out of the breaker face in a standard panel enclosure. At 415 V and 440 V it still holds 242 kA, dropping to 187 kA at 500 V and 52.5 kA at 690 V. If your transformer is oversized or you're close to the substation, verify your SCCR study against the 242 kA at 440 V curve — that's the conservative bound for 480 V systems. ## Thermal derating and continuous current At 55 °C it derates to 240 A, at 60 °C to 235 A, at 65 °C to 230 A, and at 70 °C to 225 A. In a sealed stainless panel with multiple breakers ganged, factor this into your thermal budget. ## Physical fit and auxiliary contacts Comes with 2 HP auxiliary switches factory-installed (high-performance type, rated for control-circuit isolation). The base switch (without auxiliaries) is order code 3VA2325-7MN32-0AA0. This -0AB0 suffix adds the 2 HP auxiliary switches at the factory rather than as a field-installed kit.","metaTitle":"Siemens 3VA2325-7MN32-0AB0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2325-7MN32-0AB0 SENTRON molded case circuit breaker, 250 A at 40 °C, 3-pole, ETU350M trip unit, 330 kA at 240 V.
