Current rating holds at 125 A from 40 °C through 50 °C ambient, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Size the feeder accordingly. ## Duty and fit The 4-pole construction handles three-phase plus neutral switching. Power loss maxes at 28.1 W — not negligible in a sealed cabinet. If you're packing multiple breakers in a small enclosure, factor that heat into the thermal budget or you'll push the derating curve harder than the table shows.","metaTitle":"Siemens 3VA1112-6EE46-0AA0 SENTRON MCCB, 125 A, 4-Pole, 220","metaDescription":"Siemens 3VA1112-6EE46-0AA0 SENTRON molded case circuit breaker, 125 A, 4-pole, TM220 release.
