That interrupting rating drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 17 kA at 690 V — so the SCCR headroom is highest on 240 V secondary side of a distribution transformer, but still substantial on 400 V class systems. Communication function is present, which means this breaker can report status and accept commands over a bus — useful for a monitored distribution panel where you need to know the breaker state without walking the line. At 45 °C it derates to 600 A, at 50 °C to 570 A, at 55 °C to 540 A, at 60 °C to 510 A, at 65 °C to 480 A, and at 70 °C to 450 A. The breaker dissipates up to 162 W at full rated current, so ventilation or a larger enclosure may be needed to stay below the 70 °C operating maximum.","metaTitle":"Siemens 3VA2463-5KP32-0JA0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0JA0 molded case circuit breaker, 630 A rated at 40 °C, 187 kA breaking at 240 V.
