The interrupting ratings climb to 187 kA at 240 V, then taper to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — a curve that tells you this breaker is sized for high-fault industrial distribution, not light commercial service. At 690 V the 17 kA figure still clears most motor-circuit faults, but verify your available fault current against that value before committing the BOM line. Thermal derating is published: full 250 A through 50 °C, then 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C. ## Lifecycle and sourcing reality — active, not orphaned The basic switch (the internal switching mechanism) is order code 3VA2325-5MN32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL33 — both are serviceable sub-assemblies if a field repair ever needs to swap the trip unit without replacing the entire breaker. ## Integration — panel footprint and wiring The 3VA2325-5MN32-0KC0 measures 248 mm high, 138 mm wide, and 110 mm deep — a standard 3-pole MCCB footprint that fits most low-voltage switchgear cubicles and distribution panels without re-drilling the mounting plate. Depth of 110 mm leaves clearance for rear-connection busbars or cable lugs. Phase-failure detection is built into the ETU350M trip unit, so no external phase-loss relay is needed for motor protection applications.","metaTitle":"Siemens 3VA2325-5MN32-0KC0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2325-5MN32-0KC0 molded case circuit breaker, 250 A rated, 3-pole, ETU350M electronic trip, 187 kA at 240 V.
