The Siemens SENTRON 3VA2463-5KP32-0HC0 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. That 187 kA figure drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and further to 9 kA at 690 V — the SCCR headroom you need for high-fault installations like transformer secondaries or large motor control centers. The continuous current derates predictably with ambient temperature: 600 A at 45 °C, 570 A at 50 °C, down to 450 A at 70 °C. It also carries a communication function via the SENTRON communication module.
