The interrupting capacity at 240 V is 242 kA, at 415 V it holds at 187 kA, and at 690 V it drops to 9 kA. ## Built-in release and auxiliary switching The base switch is order code 3VA2463-6HN32-0AA0; the -0DC0 suffix adds the UVR and aux package. No communication module is fitted, so this is a standalone line-protection device — no Modbus or PROFIBUS bridge inside the housing. ## Physical fit — DIN-rail and enclosure integration Dimensions are 248 mm height, 138 mm width, 110 mm depth — a standard 3-pole MCCB footprint for 630 A frame size. Width of 138 mm is the panel cutout dimension; verify gland-plate knockouts match before drilling. ## Temperature derating curve — what the table tells you The continuous-current rating is published at seven ambient points from 40 °C to 70 °C: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. That is a linear derating of roughly 2.2 A per °C above 40 °C. The maximum power loss is 164.5 W, which factors into enclosure thermal rise calculations.","metaTitle":"Siemens 3VA2463-6HN32-0DC0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0DC0 molded case circuit breaker, 630 A continuous at 40 °C, 242 kA breaking at 240 V. 3-pole, line protection, undervoltage release.
