At 415 V and 440 V the interrupting rating is still 121 kA, and it holds 79 kA at 500 V, so it covers most industrial distribution voltages without needing a current-limiting fuse upstream. The 63 A rating holds at ambient temperatures up to 50 °C without derating — at 55 °C it drops to 60.6 A, at 60 °C to 58.3 A, and at 70 °C to 53.6 A. If your panel runs hot (enclosed switchgear, solar combiner, or near a heat source), the 63 A frame still gives you headroom at 50 °C; above that, apply the derating curve. The rated insulation voltage Ui is 800 V, so the breaker is electrically rated for 690 V systems (the interrupting rating at 690 V is 3.4 kA, confirming it is not intended for primary fault clearing at that voltage — use it as a load-break switch or backup device on 690 V lines). The depth of 86 mm means it clears most standard enclosure back panels without a sub-panel extension. It ships without auxiliary contacts (auxiliary contact version: without), but the integrated undervoltage release (UVR) is factory-fitted — order code 3VA9608-0BB11 for the release module if you need a spare. The ETU850 electronic trip unit provides communication capability (Communication Function: Yes), so it can interface with a higher-level energy management or SCADA system over the SENTRON bus.","metaTitle":"Siemens 3VA2063-5KP32-0BA0 SENTRON MCCB, 63A, 187kA at 240V","metaDescription":"Siemens 3VA2063-5KP32-0BA0 SENTRON molded case circuit breaker, 63A rated continuous current, 187kA interrupting at 240V.
