Current rating is temperature-dependent: 630 A at 40 °C, derating to 450 A at 70 °C ambient. The adjustable thermal-magnetic trip range spans 945 A minimum to 5 670 A maximum, with a full-scale value of 630 A. Power loss maxes at 162 W. Mounts in a 138 mm wide by 248 mm tall by 110 mm deep footprint. The 3-pole body fits standard MCCB panel cutouts; verify bus-bar spacing against the 138 mm width before laying out the gland plate. ## Accessories and Configuration No undervoltage release fitted. Communication function is present; no other measurement function.","metaTitle":"Siemens 3VA2463-5JQ32-0KC0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0KC0 molded case circuit breaker, 630 A rated at 40 °C, 3-pole, 187 kA at 240 V.
