The Siemens 3VA1063-3ED32-0CC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release. This breaker carries 75.6 kA breaking capacity at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V — figures that tell you it can interrupt fault currents up to those levels without upstream coordination failure. The auxiliary contacts are wired separately from the main power path, so they report the breaker's actual mechanical position, not just the trip signal. It mounts on a DIN rail or panel-mount baseplate, occupying 76.2 mm width (roughly 4.5 standard module spaces) and 130 mm height.
Above 50 °C, the breaker must be derated: 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 your panel runs hot — near a drive cabinet or in a non-climate-controlled enclosure — use the 55 °C or 60 °C column to size the breaker.
