The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, and still clears 75.6 kA at 500 V, so it handles high-fault industrial feeds without cascading upstream. It's a motor protection design, not a plain distribution breaker — the trip curve and accessories are matched to motor starting profiles.
The 3VA2163-5MN32-0DL0 measures 105 mm wide, 181 mm tall, and 86 mm deep — standard MCCB footprint for a 3-pole 63 A frame. Maximum power loss is 6.5 W, which is modest for this rating; no forced cooling needed in a typical IP54 enclosure.
