The interrupting capacity hits 220 kA at 240 V AC, dropping to 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V — so at 480 V typical of North American industrial panels you're looking at the 121 kA curve. That's a serious fault-clearing number; it keeps downstream gear safe on high-available-fault buswork. Full 630 A rating holds from 40 °C to 50 °C ambient; above that it steps down — 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, 583 A at 70 °C. That's a gentle slope, so a warm enclosure doesn't gut the breaker. The 184 mm width, 248 mm height, and 110 mm depth (7.24 x 9.76 x 4.33 inches) mean it fits standard MCCB mounting footprints; the IP40 front keeps dust out of the panel face but isn't rated for washdown environments.","metaTitle":"Siemens 3VA1463-6FF42-0AA0 SENTRON MCCB, 315 A, 220 kA","metaDescription":"Siemens 3VA1463-6FF42-0AA0 SENTRON molded case circuit breaker. 315 A, 4-pole, TM240 release. 220 kA at 240 V.
