The continuous current rating holds at 200 A from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C — the full thermal curve is on the nameplate, so panel builders can size for elevated ambient without guessing. The case measures 70 mm deep, 140 mm wide, and 158 mm high. ## Environmental and approvals The 3VA series carries UL, CSA, and IEC certifications per the SENTRON platform.","metaTitle":"SENTRON 3VA1220-5EF42-0DA0 Molded Case Circuit Breaker, 200","metaDescription":"SENTRON 3VA1220-5EF42-0DA0 molded case circuit breaker, 200 A rated at 40 °C, 4-pole, 187 kA breaking at 240 V.
