The 200 A rating holds flat from 40 °C through 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C — so if your panel ambient runs at 55 °C, you lose 8 A of headroom; plan the load accordingly. It is designated as a starter protection version, meaning the electronic trip unit (ETU310M) is configured for motor-starting profiles — it handles the inrush without nuisance tripping while still providing short-circuit and overload protection for the motor branch. ## Trip unit and auxiliary releases If you need those, you are looking at a different order code in the 3VA2 family. ## Mechanical fit and panel integration If you are swapping an older 200 A MCCB, measure your existing cutout against these numbers before ordering. The 20 000-cycle mechanical endurance is typical for a 200 A frame — fine for distribution switching, but if you are cycling it daily as a disconnect, consider a dedicated switch.","metaTitle":"Siemens 3VA2220-7MS32-0KA0 SENTRON MCCB, 200 A, 3-pole, 330","metaDescription":"Siemens SENTRON 3VA2220-7MS32-0KA0 molded case circuit breaker, 200 A rated, 3-pole, interrupting up to 330 kA at 240 V.
