What this MCCB delivers
The Siemens SENTRON 3VA2220-7MS32-0KC0 is a 3-pole molded case circuit breaker rated for 200 A continuously from 40 °C through 70 °C, meaning you do not need to derate for elevated panel ambient within that range — a real advantage when the breaker sits near other heat sources in a crowded enclosure. Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, and 187 kA at 500 V; at 690 V it still clears 5.2 kA.
That 105 mm width across three poles is standard for this class of SENTRON MCCB — it aligns with the same DIN-rail or screw-mount footprint used by the 3VA2 family, so a panel designed for a 3VA2116 or 3VA2225 will accept this unit without drilling new holes.
