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 330 kA figure at 240 V means it can be placed on high-fault panels without cascading to upstream fuses — a common concern on low-voltage distribution in industrial plants. Designed specifically for starter protection (motor branch-circuit duty), it ships with a shunt trip (STL) and two HQ auxiliary switches, but no undervoltage release, no phase-failure detection, and no ground-fault monitoring — so if your application needs those, you will add external modules or choose a different variant.
Dimensions and panel fit
The breaker measures 86 mm deep, 105 mm wide, and 181 mm high. 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.
