The 3VA2063-8KQ32-0AA0 keeps its full 63 A rating right up to the 70 °C operating maximum. Breaking capacity is specified at five voltage points: 440 kA at 240 V, 330 kA at 415 V, 330 kA at 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. For a 480 V panel, interpolate between the 440 V and 500 V figures — roughly 275 kA available. That is a high-interrupting frame for a 63 A MCCB; it handles most transformer-fed secondary faults without cascading upstream. That means it can report trip events and leakage current to a BMS or PLC without an add-on module — useful for coordinated ground-fault schemes in data-center or industrial distribution.","metaTitle":"Siemens SENTRON 3VA2063-8KQ32-0AA0 MCCB, 63 A, 3-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2063-8KQ32-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, 440 kA breaking at 240 V.
