The Siemens 3VA1063-2ED32-0JA0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A at 40 °C through 50 °C, with a slight thermal derating to 58 A at 70 °C. Its 52.5 kA breaking capacity at 240 V AC drops to 32 kA at 415 V and 7.5 kA at 690 V — enough for most distribution panels and motor branch circuits in commercial and light industrial plants.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB that mounts on a DIN rail or panel-mount adapter. The 70 mm depth (2.76 in) is standard for the 3VA frame size; check gland-plate clearance if back-panel wiring is tight. Max power loss is 17.3 W, so ventilation in a sealed enclosure is worth a look if you're grouping several breakers.
For selective coordination downstream of a larger MCCB or upstream of a fused disconnect, the 52.5 kA SCCR at 240 V gives solid fault-clearing headroom. At 415 V the 32 kA rating still covers most industrial service-entrance fault levels.
