In a warm panel — say 55 °C internal ambient — you lose only 6 A, so the 200 A frame still comfortably protects a 190 A continuous load. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. The 105 mm width is the standard 3-pole MCCB footprint for the SENTRON 3VA platform — fits the same panel cutout and bus-bar spacing as the 3VA1112-5EF32-0CA0 and other 3-pole 3VA frames. Front IP40 protection; no auxiliary contact slot populated, so if you need a status signal you'll add the 3VA9608-0BB25 auxiliary trip accessory.","metaTitle":"Siemens 3VA1220-5EF32-0DA0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0DA0 molded case circuit breaker, 200 A rated continuous current, 3-pole, line protection, undervoltage release.
