What this MCCB is and what it does
The Siemens 3VA2220-7MS32-0AH0 is a SENTRON molded case circuit breaker (MCCB) designed for starter protection — meaning it's built to sit ahead of a motor starter combination, handling both overload and short-circuit protection in a single compact package. Rated 200 A continuous at 40 °C, it's a 3-pole unit with a trip indicator and a 3 000 A maximum interrupt rating, but the real story is the breaking capacity: 330 kA at 240 V, 242 kA at 415 V, and still 187 kA at 500 V. That's serious fault-clearing capability for industrial distribution where high available fault current is a given.
What the ratings mean for your panel
The 200 A rating holds flat from 40 °C all the way to 70 °C — no derating needed in a warm enclosure, which is rare for an MCCB. That means you can size the breaker for the motor full-load amps without adding a temperature margin. The 86 mm depth and 105 mm width fit standard MCCB mounting footprints; it's a direct panel-mount unit, not DIN-rail, so plan for a cutout or backplate. Power loss is 46 W maximum, so factor that into enclosure thermal calculations.
Auxiliary switch configuration
The breaker ships with 2 auxiliary switches plus 1 trip alarm switch (HQ type) built in. That's enough for remote status indication — auxiliary contacts for open/closed, plus a separate alarm contact that only changes state on a trip event. No undervoltage release, no ground-fault monitoring, no communication module on this variant. If you need those, look at the 3VA2 family options.
