Breaking capacity hits 330 kA at 415 V and 440 kA at 240 V — that's high enough to sit upstream of a busway or a transformer secondary without worrying about cascading failure during a bolted fault. The 63 A rating holds flat across the entire ambient range from 40 °C to 70 °C, so you don't lose headroom in a hot enclosure or a summer peaking panel. It carries a communication function, which means it can talk to a higher-level monitoring system — useful for remote trip indication or load-shedding coordination without adding a separate module. ## Footprint and integration Dimensions are 181 mm high, 140 mm wide, 86 mm deep — a standard SENTRON 3VA2 footprint that drops into the same DIN-rail or mounting-plate cutout as the rest of the series. Power loss is capped at 3.1 W, so ventilation requirements are minimal even in a densely packed panel.","metaTitle":"Siemens 3VA2163-8KQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2163-8KQ46-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, 330 kA breaking at 415 V.
