Interrupting capacity runs from 330 kA at 240 V down to 3 kA at 690 V. At 415 V and 440 V it holds 242 kA — that's the figure most distribution panels will reference for SCCR compliance. The 756 A maximum and 95 A minimum on the interrupting range tell you the breaker can clear faults well above its 63 A frame, which is typical for a line-protection MCCB sized to handle inrush without nuisance trips. Footprint is 86 mm deep, 140 mm wide, 181 mm tall — a 4-pole MCCB that fits standard Siemens SENTRON mounting plates and busbar systems.","metaTitle":"Siemens 3VA2063-7KQ46-0KB0 SENTRON MCCB, 63 A, 4-Pole, 756 A","metaDescription":"Siemens 3VA2063-7KQ46-0KB0 SENTRON molded case circuit breaker, 63 A rated, 4-pole, interrupting 330 kA at 240 V.
