That is a steep SCCR curve — the part is clearly designed for low-voltage high-fault applications (think transformer secondaries or large busway feeds) where available fault current is extreme. At 690 V the 17 kA rating still covers most industrial motor-control center main breakers. The 4-pole frame also handles DC switching per the 3VA device manual, though the AC ratings are the headline numbers here. Rated 250 A from 40 °C through 50 °C, then it begins to taper: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, 223 A at 70 °C. The 70 mm depth and 140 mm width fit a standard MCCB footprint — no oddball cutout. The lifecycle stage is listed as current — meaning this is an active, in-production catalog number from Siemens. No PCN or phase-out notice is on record.","metaTitle":"Siemens 3VA1225-5EE42-0AA0 SENTRON MCCB, 250A 4-Pole, TM220","metaDescription":"Siemens 3VA1225-5EE42-0AA0 SENTRON molded case circuit breaker, 250 A at 40 °C, 4-pole, TM220 release. 187 kA at 240 V.
