It is designed without ground-fault monitoring or communication functions, and no trip indicator or voltage trigger is present. The 63 A rating holds flat from 40 °C through 50 °C, then derates gradually: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 19.8 W. The 3-pole footprint fits standard SENTRON panel cutouts and busbar systems. The 70 mm depth leaves clearance for rear-connected cable lugs or busbar adapters in a typical 200 mm deep enclosure.","metaTitle":"Siemens 3VA1063-3ED32-0DC0 SENTRON MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1063-3ED32-0DC0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, 75.6 kA breaking at 240 V.
