It is built for main feeder or large branch-circuit duty in distribution panels, switchboards, and industrial enclosures — the class of part that sits between the transformer secondary and the downstream load centers. This breaker carries 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. For a 480 V panel in North America, the relevant figure is the 440 V rating (75.6 kA), which covers the typical 480Y/277 V service. At 690 V, the 17 kA Icu still clears most industrial fault levels, but if your transformer is large enough to push 25 kA at 690 V, you need a higher-rated frame. The thermal derating curve is flat from 40 °C to 50 °C at 200 A (–), then drops to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If your panel ambient hits 55 °C, you lose 6 A — plan the load accordingly. Power loss at full rating is 42 W maximum, which matters for heat buildup in a sealed enclosure.","metaTitle":"Siemens 3VA1220-6EF32-0AD0 SENTRON MCCB, 200A, 3-Pole, 220kA","metaDescription":"Siemens SENTRON 3VA1220-6EF32-0AD0 molded case circuit breaker, 200A rated at 40-50°C, 3-pole, TM240 release, 220kA at 240V.
