Breaking capacity reaches 121 kA at 240 VAC, 75.6 kA at 415 VAC, and 11.9 kA at 690 VAC — these numbers define the available fault current the breaker can safely interrupt at each system voltage, which is the primary selectivity and SCCR check for the distribution board. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — fits standard MCCB panel cutouts and busbar centers for a 3-pole 63 A frame.","metaTitle":"Siemens 3VA1063-4ED32-0KC0 SENTRON MCCB, 63 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1063-4ED32-0KC0 molded case circuit breaker, 63 A rated, 3-pole, 121 kA breaking capacity at 240 VAC.
