What this 3VA2463-6HN32-0AB0 brings to the panel
The Siemens SENTRON 3VA2463-6HN32-0AB0 is a 3-pole molded case circuit breaker rated for 630 A continuous current at 40 °C, with an interrupting capacity of 242 kA at 240 V.
That 110 mm depth is a key number for shallow enclosures or gland-plate clearance — it's shallower than many MCCBs in this current class, so it fits where a deeper breaker would hit the back wall.
Derating and ambient temperature
The 630 A rating holds only at 40 °C ambient. As the panel warms up, the breaker derates: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C.
Auxiliary contacts and accessories
There is no undervoltage release, no shunt trip, no ground-fault monitoring, and no voltage trip on this order code. If you need those, you'd look at a different suffix.
