Its breaking capacity hits 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V, giving you selectivity headroom for high-fault utility feeds or transformer secondaries. The 63 A full-scale value is the frame rating; the adjustable thermal-magnetic trip range spans 95 A minimum to 756 A maximum, so this breaker covers downstream feeders from moderate motor circuits up to high-current bus ties. The 3.1 W maximum power loss keeps enclosure heat rise low — relevant when packing multiple breakers in a closed panel. The communication function allows remote trip indication and load monitoring, which is useful for predictive maintenance on continuous-process lines. The 3-pole footprint matches standard SENTRON 3VA2 series cutouts; verify the 105 mm width against existing busbar spacing if retrofitting into an older panel.","metaTitle":"Siemens 3VA2163-8KQ36-0AA0 SENTRON MCCB, 63 A, 3-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2163-8KQ36-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, 440 kA breaking at 240 V.
