Its interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V — numbers that tell you it's built for high-fault utility or transformer-fed services where a standard MCCB would weld shut. The 630 A frame carries a fixed magnetic trip at 5 670 A (9x In), so it's a fixed-trip line protection breaker, not an adjustable-frame for motor protection. You spec it for the feeder, not the load.
At 40 °C ambient you get the full 630 A; derate to 520 A at 70 °C. That's a 17 % drop across the range — plan your enclosure ventilation if the breaker sits near other heat sources. The 138 mm width is a 3-pole frame that fits standard Siemens SENTRON mounting plates and busbar systems; the 110 mm depth leaves room behind a 200 mm deep enclosure door. Maximum power loss is 164.5 W at rated load — that's the heat you need to extract from the panel. Not trivial; factor it into your thermal calculation if you're stacking multiple breakers.
The UVR means the breaker drops on loss of control voltage — common for emergency-stop chains or undervoltage protection schemes. The basic switch core is order code 3VA2463-7HN32-0AA0; the -0DL0 suffix adds the UVR and the HQ alarm package. If your BOM already carries the -0AA0, this is a drop-in swap with extra functionality. A trip indicator is present, and there is no voltage-trigger or communication function — it's a standalone thermal-magnetic breaker, not a smart unit.
