The 200 A rating holds flat from 40 °C through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Footprint is 140 mm wide, 158 mm tall, 70 mm deep. That width is the standard 4-pole MCCB envelope for the 3VA1 frame — fits most DIN-rail-mount or panel-mount backplates without surprises. No undervoltage release, no voltage trip, no communication module on this order code, so wiring is limited to the line and load power connections plus the three auxiliary switch terminals (HQ type). If your BOM calls for shunt trip or UVR, this isn't the variant; you'd step to a 3VA1 with the appropriate suffix.","metaTitle":"Siemens 3VA1220-5EF42-0AD0 SENTRON MCCB, 200A, 4-Pole, 187kA","metaDescription":"Siemens 3VA1220-5EF42-0AD0 SENTRON molded case circuit breaker, 200A rated at 40°C, 4-pole, 187kA interrupting at 240V.
