That puts it in a solid range for most distribution panels behind a transformer of moderate size. At 440 V it drops to 13.6 kA, and at 690 V it still holds 7.5 kA, which matters if you are on a 690 V mining or marine system. ## Current derating and ambient temperature The breaker holds full 63 A from 40 °C up through 50 °C without any derating — that covers most ventilated enclosures. Above that, it drops: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If you are packing this into a hot cabinet or near other heat sources, account for that taper. Depth is 70 mm, so it does not stick out far from the mounting surface. The auxiliary contact block (2 form-C aux + 1 trip alarm) is integrated; the shunt trip coil is specified separately as 3VA9688-0BL33 if you need a replacement or spare.","metaTitle":"Siemens 3VA1063-2ED32-0KH0 SENTRON MCCB, 63 A, 3-Pole","metaDescription":"Siemens 3VA1063-2ED32-0KH0 SENTRON 3-pole molded case circuit breaker, rated 63 A continuous at 40 °C, interrupting 32 kA at 415 V.
