Above that, the thermal-magnetic or electronic trip unit must be derated: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. For panel builders, this means the 3VA1220-5GF42-0JC0 can be installed in a 50 °C enclosure without downsizing the main conductors, but above that temperature the load current must be reduced per the published curve. ## Physical Fit and Auxiliary Components Dimensions are 158 mm high, 140 mm wide, and 70 mm deep — a 4-pole frame that occupies roughly 5.5 inches of DIN-rail or panel-mount width.","metaTitle":"Siemens 3VA1220-5GF42-0JC0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0JC0 molded case circuit breaker, 200 A, 4-pole, 187 kA interrupting at 240 V.
