This MCCB delivers 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. For a 480 V panel (common in North America), the 36 kA at 440 V figure is the closest published rating; the actual SCCR at 480 V will sit between the 415 V and 440 V curves. Verify coordination with the upstream transformer impedance before committing the BOM line. ## Thermal derating and panel fill Above that, derating is linear: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. Dimensions are 105 mm wide × 158 mm high × 70 mm deep, which is the standard 3-pole SENTRON 3VA footprint; it occupies three 35 mm DIN-rail modules. ## Release and accessory configuration The undervoltage release (UVR) is factory-installed; its order code is 3VA9608-0BB25. There is no auxiliary contact block, no ground-fault module, no communication function, and no voltage-trip or shunt-trip option on this variant. The basic switch assembly carries the code 3VA12206EF320AA0. If you need remote signaling or GF protection, this is not the variant — step up to the 3VA1 with the appropriate suffix. No successor has been announced. For a line-down replacement, this is a straight drop-in for any panel originally built with the 3VA1220-6EF32-0DA0. Standard compliance documentation (CE, UL, CSA, IEC 60947-2) is provided with the breaker; RoHS and REACH declarations are available from Siemens upon request.","metaTitle":"Siemens 3VA1220-6EF32-0DA0 SENTRON MCCB, 200 A, 220 kA at 24","metaDescription":"Siemens 3VA1220-6EF32-0DA0 SENTRON molded case circuit breaker, 200 A rated continuous current, 220 kA breaking at 240 V. 3-pole, TM240 release, undervoltage release included.
