Per the datasheet, the continuous current derates with ambient temperature: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. A communication function is present, and the trip indicator is not fitted. The initial value of the adjustable overload protection is 126 A, with a full-scale setting of 630 A. The design is line protection, meaning it is intended for feeder or main breaker duty, not motor branch-circuit protection (which would require a different trip curve). Dimensions are 248 mm height, 138 mm width, and 110 mm depth. The MCCB is designed for panel mounting — typically bolted to a backplate or mounted on a DIN rail adapter (not included). The 110 mm depth is the body depth; allow clearance for the undervoltage release coil and any communication module wiring.","metaTitle":"Siemens 3VA2463-5JQ32-0BA0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0BA0 molded case circuit breaker, 630 A, 3-pole, 187 kA at 240 V.
