The SENTRON 3VA2463-8KQ32-0AA0 is a 3-pole molded case circuit breaker rated for 630 A continuous current at 40 °C, with a full-scale trip setting of 630 A and an initial trip value of 126 A. Breaking capacity is 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V.
Thermal derating and real-world fit
At 45 °C it's 600 A, at 50 °C it's 570 A, at 55 °C it's 540 A, at 60 °C it's 510 A, at 65 °C it's 480 A, and at 70 °C it's 450 A. The maximum power loss is 162 W, so ventilation matters. That's a standard MCCB footprint for this current class; it'll bolt into a SENTRON panelboard or a standalone enclosure without surprises.
Protection features and monitoring
The breaker also includes an 'other measurement function' and communication capability.
