What this MCCB is and what it handles
The 3VA2220-7MS32-0AD0 is a SENTRON molded case circuit breaker (MCCB) from Siemens, built for starter protection — meaning it's meant to sit ahead of a motor starter or soft starter, not as a main feeder breaker. It's a 3-pole unit with a continuous current rating of 200 A that holds steady all the way from 40 °C up to 70 °C ambient, so you don't lose capacity as the panel warms up. The adjustable thermal-magnetic trip unit lets you set the instantaneous pickup anywhere from 600 A to 3000 A — that's 3× to 15× the continuous rating. On a motor circuit you'd typically dial it in above the locked-rotor current to avoid nuisance trips on start-up, but still low enough to clear a bolted fault fast.
Interrupting capacity — the real number
Interrupting capacity changes with system voltage, and this breaker delivers 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 5.2 kA at 690 V. That 330 kA at 240 V is a high-end figure — it'll handle a fault right at the secondary of a large transformer without needing a current-limiting fuse upstream. At 690 V the number drops to 5.2 kA, which is still adequate for most 690 V motor circuits where the available fault current is usually lower.
Physical fit and panel integration
The breaker measures 181 mm high, 105 mm wide, and 86 mm deep — about 7.1 by 4.1 by 3.4 inches. That 105 mm width is the standard 3-pole MCCB footprint for this frame size, so it'll drop into most panel layouts that already have a SENTRON 3VA2 or similar 200 A frame breaker. No rewiring needed if you're replacing a same-footprint unit.
