The 200 A rating holds flat from 40 °C to 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 (–). For a panel that runs warm — say 55 °C ambient — you have 194 A of headroom; above that, the breaker still delivers but you lose 6 A per 5 °C step. Rated insulation voltage is 800 V, with an operating range of -25 °C to 70 °C and storage from -40 °C to 80 °C. Full-load power dissipation is 42 W max. ## DIN-rail footprint and auxiliary switch complement Two factory-fitted auxiliary switches (HP type) are supplied with the basic switch; no additional trip indicator or voltage trigger is included. Communication-function option is absent on this variant.","metaTitle":"Siemens 3VA1220-5GF42-0AB0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0AB0 molded case circuit breaker. 200 A continuous, 4-pole, 187 kA interrupting at 240 V.
