The SENTRON 3VA2463-5KP32-0BC0 is a 3-pole molded case circuit breaker rated for 630 A continuous current at 40 °C, with a maximum breaking capacity of 187 kA at 240 V AC — that is the fault-clearing headroom you need for high-available-fault-current service-entrance or main-tie applications where the utility transformer is close to the switchboard. At 415 V and 440 V it still holds 121 kA, and at 500 V it delivers 75.6 kA; only at 690 V does the rating drop to 9 kA, so for 690 V distribution you would need a different frame or a current-limiting upstream device. The continuous current derates with ambient temperature: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C — so if your panel ambient runs above 40 °C, the actual load you can protect is lower than the nameplate 630 A.
Lifecycle and sourcing — active, quoted to order
No trip indicator is fitted on this variant, and there is no ground-fault monitoring module built in — if you need those, you would look at a different suffix within the 3VA2 family.
As a SENTRON product, this MCCB carries the usual IEC/UL certifications for molded case circuit breakers (IEC 60947-2, UL 489), and the manufacturer provides RoHS and REACH compliance declarations on request — the evidence does not list specific cert numbers, but these are standard for the series.
