The Siemens SENTRON 3VA2220-7MS32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 200 A continuous current (Iu) and carrying an interrupting capacity of 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — figures that tell you this breaker is built for high-fault-current main or feeder duty in industrial switchboards, not branch protection. 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.
