Above that, the continuous current must be derated: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The breaker measures 70 mm deep, 140 mm wide, and 158 mm high. The 4-pole form factor occupies the same footprint as other 3VA frames in the 200 A class, so a panel laid out for a 3VA1110 or 3VA2116 will accept this unit without re-drilling the mounting plate — verify the busbar tap positions for the shunt trip wiring.","metaTitle":"Siemens 3VA1220-4GF42-0JA0 SENTRON MCCB, 200 A, 4-Pole, 70 m","metaDescription":"Siemens 3VA1220-4GF42-0JA0 SENTRON molded case circuit breaker, 200 A rated, 4-pole, TM240 release, shunt trip.
