Rated current holds at 20 A from 40 °C through 55 °C ambient, then derates to 19 A at 60 °C through 70 °C — a thermal curve that matters when the breaker shares a crowded enclosure with other heat sources. Key dimensions (70 mm depth, 101.6 mm width) and the 4-pole footprint are shared across the 3VA family.","metaTitle":"Siemens 3VA1120-3EE46-0AA0 SENTRON MCCB, 20A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1120-3EE46-0AA0 molded case circuit breaker, 20A rated, 4-pole, TM220 trip unit, 75.6kA breaking capacity at 240V.
