Above that, current must be reduced: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. In a hot panel near a transformer or drive, factor in the actual ambient — a 200 A load at 60 °C would need the next frame size up. Dimensions: 70 mm deep, 140 mm wide, 158 mm high. The auxiliary switch configuration (2 HQ switches) and the shunt trip occupy the accessory slots; verify clearance above and below for the 70 mm depth when wiring.","metaTitle":"Siemens SENTRON 3VA1220-6EF42-0KC0 MCCB, 4P, 200 A, 220 kA a","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0KC0 molded case circuit breaker, 4-pole, 200 A rated at 40 °C, 220 kA breaking at 240 V.
