The interrupting ratings are the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The minimum trip threshold is 189 A, so it's not for light loads; this is a heavy iron breaker.
The 3VA2163-7MS36-0AE0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA frame size that drops into a DIN-rail or panel-mount footprint. It ships with 4 HQ auxiliary switches built in, so you get status feedback without adding external blocks. The supplied basic switch is order code 3VA2163-7MS36-0AA0, meaning the breaker itself is the same platform as the base variant; the -0AE0 suffix adds the auxiliary switch configuration. If you need those features, you're looking at a different suffix, not a different frame.
Here, you can load it to 63 A even in a hot enclosure. The 189 A minimum trip means the magnetic instantaneous pickup is set high enough to avoid nuisance trips on motor inrush but still catches a bolted fault. Power loss is 4 W maximum, negligible for thermal budgeting.
